If Trump hands the baton to him, Pence can win.
No. He won't win.
Too many of those Trump supporters are Trump -- not Pence -- supporters. If Trump is forced out, many of his supporters will leave with him, and we will see repeats of 2008 and 2012.
The docket is Trump or Clinton. One of those will be the next president. [Recall a week ago the bluster concerned what the Dems would do if Clinton was forced out.]
Pence just doesn't have the drawing power. It would sort of be like replacing Hillary with Chelsea or even Kaine. There is no real excitement for any of those.
