Editor’s Note: With fewer than 11 weeks until the Nov. 8 presidential election, many voters have yet to make up their minds. As part of an occasional series of articles, we are checking in with undecided voters for their thoughts about key issues and developments in the campaign.

INDIANAPOLIS — Jason Thornbury was ready to vote to put Mike Pence back in the Statehouse for a second term. But his admiration for the governor isn’t enough to convince him to put Pence’s running mate, Donald Trump, in the White House.

“Pence is a great speaker and appears to be quite capable, but nothing he says at this point sways me one way or another about Donald Trump,” said Thornbury, a self-described conservative who wishes it was Pence at the top of the ticket, instead of Trump.

Thornbury, 45, of Brownsburg, is among those voters who’ve not decided whom they’ll back – or even if they’ll vote – in the upcoming presidential election.

Many undecided voters say they find both Trump and his Democratic opponent, Hillary Clinton, unappealing. Yet, they also question the practicality of supporting a third-party candidate.

Thornbury’s reluctance to vote for Trump because he selected Pence as his vice president doesn’t surprise Christine Mathews, a pollster in Washington, D.C., who originally hails from Kokomo.

“Trump and Clinton are such well-known and polarizing figures, I don’t think their VP choices are going to supersede or mitigate anyone’s feelings about the top of the ticket,” she said. “If you’re undecided at this point, it’s because both candidates are unacceptable.”

Matthew Duncan wishes it wasn’t so.

Duncan, an Indiana University law school student, calls himself a reliably Republican voter.

He said Pence, who spent six terms in Congress and is popular among social conservatives, was Trump’s best choice for a running-mate to win over doubtful GOP voters. Duncan said Pence is “more likable” than Trump.

Still, he said, that’s not enough.

“There is most likely nothing Gov. Pence could say or do to persuade me to vote for Donald Trump,” Duncan said. “Voting for Trump would require major changes in tone and policy positions from the candidate, himself.”

Pence was a surprise pick for some, when Trump chose him just before the Republican National Convention in July over better-known alternatives including New Jersey Gov. Chris Christie and former House Speaker Newt Gingrich.

The celebrity real estate mogul reportedly selected Pence on the advice of then-campaign manager Paul Manafort, who convinced him of the need to nod to conservatives in a bid to win Midwest and Rust Belt states.

At the time, Pence was little known nationally – a status that also plagued Clinton’s running mate, Virginia Sen. Tim Kaine.

A national Gallup Poll early this month indicates that’s changed somewhat for both vice presidential candidates.

Pence’s favorability ratings have doubled, from 18 percent to 36 percent, since the July convention, according to the Aug. 10 poll.

Kaine’s favorability numbers went up by less than 10 points.

More people know Pence now. The percentage of those who’d never heard of him or have no opinion of him dropped from 65 percent to 39 percent in the wake of the GOP convention. More Republican voters say they like him.

Whether any of that makes a difference in Indiana, or elsewhere, remains to be seen.

Matthews, whose Bellwether Research works for Republican candidates, says historically the vice-presidential candidate has little or no impact on outcome of the vote in his home state. The presidential candidate usually has a home-state advantage, however.

In Indiana, some undecided voters said they’re convinced that Pence may even do more harm than good.

School nurse Patricia Moore, of Logansport, said she doesn’t trust Clinton enough to vote for her.

She’s also alarmed at Trump’s divisive rhetoric and impulsive decisions.

“I must say, when he added Mike Pence, it even made we waiver more,” she said. “I am not a fan of Pence.”

Pence’s repeated disagreement with the state public schools superintendent, Glenda Ritz, an opponent of his expanded private school voucher program, troubles Moore.

She half-jokingly said she might change her mind if Trump would follow her advice: “Donald, fire him and let’s find a new running mate.”

Megan Wagoner, 19, who plans to vote in her first presidential election this year but hasn’t decided for whom, understands the sentiment.

 She’s said Pence’s socially conservative views and actions – especially his opposition to expanded civil rights for gays and lesbians – will hurt Trump among young voters who are already staying away from the GOP ticket.

As of early this month, national polls showed Trump in a fourth-place finish among voters ages 18 to 29, trailing Clinton as well as Libertarian Gary Johnson and the Green Party’s Jill Stein.

Wagoner said Pence has alienated voters in Indianapolis, where she lives.

 “If Pence is un-liked in his own state capital, why should we expect the nation to like him?” she said. “I’m not faithful to Gov. Pence, even though he represents my home state.”
