Mike Pence says Trump is unfit for office and a vote for him is a vote against the Constitution, but he makes no excuses for sticking with him for four years and says he will still support him when he inevitably gets the nomination.
Could someone be more craven than that?
Yup. Republicans have certainly backed themselves into a corner.
People like Pence make a big deal about how "someone who violates the constitution shouldn't be president", but in order to appear in any of the republican debates he has to sign a pledge that he will support the eventual republican candidate, even if its Trump, someone he claimed 'shouldn't be president'.
So either he is lying when he makes his claim about the president/constitution, or he is lying when he said he will support the eventual nominee.
Ironically, the republicans probably wanted to make the requirement to "support the nominee" in order to bring Trump to heal, but he's probably just going to ignore that pledge anyways. (Assuming he bothers with the debates in the first place.)
