COLUMBUS, Ohio (WCMH) – When Ohio U.S. Sen. Rob Portman endorsed Jane Timken two weeks ago in the Republican primary to succeed him, he said he was confident in the former state party chair’s ability to win the primary and general elections.
But his nod may have hurt Timken more than it helped her, new independent polling commissioned by NBC4 shows, and it’s not Portman’s endorsement in Ohio’s Senate race that matters most – it’s a former president’s.
Just 19% of likely GOP primary voters said Portman’s endorsement makes them more likely to vote for Timken, per a late February survey by Emerson College pollsters in partnership with NBC4 and The Hill. Twice that number – 38% – said it makes them less likely to vote for her.
The remaining 43% of respondents said Portman’s endorsement made no difference at all.
Timken’s campaign pushed back in a statement, however, saying she is “incredibly proud” to have Portman’s support.
“These numbers are a joke,” communications director Mandi Marritt said, in part. “Rob Portman is a nationally renowned conservative leader with a matchless record of delivering conservative results for the State of Ohio.”
The campaign exclusively provided to NBC4 two internal polls from this year that gives Portman a 58%-to-33% favorable/unfavorable rating among likely GOP primary voters and also found 51% would be more likely to vote for Timken after Portman’s endorsement, vs. 29% who wouldn’t.
Polls commissioned by campaigns, however, often overly favor the supported candidate and their agenda. Portman’s endorsement, though, is not toxic, as the Cincinnati Enquirer reported this month most candidates in the field wanted the retiring senator’s endorsement.
But Portman “doesn’t really matter much anymore” in the primary, Ohio State University political science professor emeritus Paul Beck said, noting declining popularity among conservative Ohio voters.
“Portman may have seen the writing on the wall that his popularity as a senator in Republican circles was declining over time,” Beck said. “He wasn’t sufficiently supportive of Trump, that was the problem.”
The last independent poll of Ohio’s GOP senate race before Portman’s endorsement was a Feb. 8-10 Trafalgar Group survey that had Timken in fifth place with 10%.
In this Emerson poll about a week after the announcement, Timken is again in fifth but with 6%. Four in 10 of those likely GOP primary voters, however, are still undecided.
The results of Portman’s endorsement contrast with the 62% of voters who told Emerson an endorsement from former President Donald Trump would make them more likely to vote for that candidate in the May 3 election. Twenty-one percent said it would make no difference, and only 18% said it would make them less likely.
“That shows that Portman’s endorsement, in comparison to Trump’s endorsement, holds much less weight among the Republican primary electorate,” Emerson’s director of survey operations Isabel Holloway said.
Portman’s office did not return a request to comment on the Emerson results.
About the Emerson poll
Between Feb. 25 and 26, Emerson College Polling surveyed 410 likely voters in Ohio’s Republican primary using text-to-web, an online panel, and automated phone calls. Results were weighted by gender, age, education, race, and region based on 2020 election turnout.
The endorsement questions each have a 4.8-point margin of error. That means a result could theoretically lose or gain 9.6% if the poll were done again.
For most polls, you can read the margin of error (MoE) like this: If the poll were to be done again 100 times, in 95 of those times the results would be within “X” percentage points of the original.
So let’s say a national poll of a sampling of registered voters, with an MoE of +/- 3, has:
You can be 95% certain that a hypothetical poll of all registered U.S. voters would yield results between these extremes:
Trump endorsement may decide Senate race
Emerson’s poll found Ohio’s GOP senate race has “no clear frontrunner” two months from Election Day, Holloway said, with Mike Gibbons and Josh Mandel on top and “a couple of other candidates that are still kind of in that conversation.”
The former president’s endorsement, then, could make a big difference.
“Trump has been pretty good in general about not wanting to waste his endorsement on somebody who he doesn't think can win,” Beck said.
Much of the GOP field has tried to prove they are the most pro-Trump candidate. Multiple candidates have met with Trump at his home in Florida, and it’s hard to find a TV ad from those candidates that doesn’t mention him.
Timken was chair of the Ohio Republican Party while Trump was in office, a job that had her “in the trenches fighting” for his agenda, she told Cleveland’s WJW-TV last year.
“There’s lots of candidates in this race that are all talk. I’m the only one that actually delivered results for President Trump,” she said, noting his 8-point win here in 2020.
“I would obviously welcome President Trump’s endorsement,” she added. “And I think he’s going to make a big impact in this race.”
On the same day Portman endorsed Timken, so did Kellyanne Conway, Trump’s former top advisor.
But will Trump endorse anyone?
Whether the former president will endorse in either Ohio’s senate or governor primaries is yet to be seen.
“He may not. We don't know for sure,” Beck said. “My guess is he will want to make an endorsement in the gubernatorial race because he's not a big fan of Michael DeWine.”
DeWine supported Trump’s reelection in 2020, but he sometimes distanced himself from Trump’s more controversial policies and actions. The governor's top two challengers, Canal Winchester farmer Joe Blystone and former Northeast Ohio Congressman Jim Renacci, are running to his right.
Emerson’s poll last week, however, found Blystone (20%) and Renacci (9%) are currently splitting the anti-DeWine vote. However, more likely voters said they are still undecided (36%) than said they plan to vote for DeWine (34%).
“As (DeWine’s) number is so low at this point in comparison to the undecided number,” Holloway said, “it'll be interesting to see if he actively courts that Trump endorsement going forward to bolster his standing.”
In making an endorsement decision in both the governor and senate races, Beck said Trump will look at the polls but also what candidates have said about him since his political rise six years ago.
Hurting some GOP senate candidates, he said, is their reluctance to support Trump in the beginnings of his 2016 campaign. JD Vance, for example, has been dinged by other candidates for calling Trump “an idiot” and “reprehensible” before coming around to him.
“One thing we know about Trump, unlike voters, is that Trump has a long memory,” Beck said. “He remembers these things, and these may come into play as he decides who he is going to endorse, if he endorses anybody.”
What about a Biden endorsement?
On the Democratic side of both races, Beck noted President Joe Biden is unlikely to endorse, even though gubernatorial candidates Nan Whaley and John Cranley – tied at 16% according to Emerson – need to chip away at the 7 in 10 undecided voters.
“It's unusual for a president to join in to nomination contests in his own party,” Beck said.
In the Democratic senate race, Youngstown area Congressman Tim Ryan, who already has the endorsement of Ohio’s Democratic U.S. Senator Sherrod Brown, polled at 31% in Emerson’s results. The frontrunner’s three challengers are all in the single-digits, and half of likely voters in that race are still undecided.
