#NeverTrump Republicans weigh how -- or whether -- to vote on Election Day

Few say they’ll pull the lever for Democratic presidential nominee Hillary Clinton, but neither Libertarian Party nominee Gary Johnson nor Evan McMullin, an independent conservative offering himself as the unofficial GOP choice, are earning groundswell support.

Some of the anti-Trump forces say they’re so frustrated, they’ll stay home on Election Day — unless it looks like doing so would help Mr. Trump, in which case they’ll turn out to give Mrs. Clinton a boost over him.

“I will maintain my high moral principles about not voting for [her], unless it looks like Trump might carry Florida, in which case I’ll throw my principles over the side and try to prevent that,” said Mac Stipanovich, a Republican lawyer based in Florida.

“You could drill a hole in my face with a wood bit and I wouldn’t vote for Donald Trump,” said Mr. Stipanovich, who penned an open letter in May calling on Republicans to stay home or vote for Mrs. Clinton “if conscience permits.”
