Patient Pence plays the long game with an eye on 2020 race
Mike Pence has long described himself as a "Christian, a conservative and a Republican in that order".
Now, the GOP vice-presidential nominee and his priorities are facing a critical test as Donald Trump staggers from controversy to controversy.
Pence's advocacy for Trump came to a screeching, perhaps temporary, halt in the hours after Trump released a video apologising for 2005 remarks in which he describes his aggressive conduct toward women.
Pence said in a statement about Trump that he won't "condone his remarks and cannot defend them".
"We pray for his family and look forward to the opportunity he has to show what is in his heart when he goes before the nation," the Indiana governor said.
It's more evidence of the trials facing the GOP's No. 2 that could serve Pence well if he runs for the top spot in 2020.
Pence dare not speak about that possibility. To do so would assume Clinton prevails on November 8.
But plenty of people are engaging in presidential talk about Pence, including Republican members of Congress, governors, a former presidential candidate and more.
Senators Mike Lee of Utah and Mike Crapo of Idaho are calling on Trump to quit the campaign so Pence can lead the ticket. Senator Kelly Ayotte of New Hampshire says she'll write in Pence's name on the ballot - not Trump's.
Pence cancelled his appearance at a Wisconsin rally on Saturday with House Speaker Paul Ryan. Pence would have been expected to advocate for Trump.
"I'm sure he's horrified," said Mike Murphy, an Indiana public relations strategist who has known Pence for more than two decades. "We impeached Bill Clinton and we cannot impeach Trump off the ballot. But I wish there was a mechanism to do so."
Pence raised his political stock last Monday during the debate against Democrat Tim Kaine. During the 90-minute event, Pence managed to not defend Trump's indefensible behaviour, yet still sound supportive and show off his expertise on foreign policy.
The performance highlighted the gulf in political sophistication between Trump and his running mate. Pence addressed the awkwardness with a savvy statement acknowledging his own performance and preserving his alliance with Trump.
"People are saying that I won the debate," he said last Wednesday in Harrisonburg, Virginia. "From where I sat, Donald Trump's vision to make America great won the debate."
An influential Indiana conservative, Jim Bopp, who helped draft this year's Republican Party platform, said Pence "should stay the course".
Trump's words are "ill-considered and crude," Bopp said, and also "statements Mike Pence would never make".
The election is bigger than that, said Bopp, a lawyer from Terre Haute, Indiana.
"In the grand scheme of things, this is trivia vs. real life-and-death problems that we face in our foreign policy and the serious challenges that everyday Americans face because of the Obama-Clinton economy."
