Was Trump aided by Pence's evangelical support and steady hand as well as solid conservative beliefs and results?
Not in Indiana, at least not much. The Evangelical camp had already congealed behind Trump as their guy after Ben Carson dropped out, long before Pence was tapped. Trump won the IN primary bigly despite Pence backing Cruz and the nomination still being in doubt. Pence is a divisive figure in Indiana, even among a lot of Republicans, and almost lost to John Gregg and his Mustache in 2012.
I have serious doubts that it helped at all nationwide. The kind of voters Pence appeals to are the kind of voters who would vote anyone with an R next to his name for President.
The kind of voters who backed Cruz are the reason Trump lost the Popular vote and the reason both Romney and McCain aren't President.
