They want to vote for Kasich. If they can get enough Electors to do this in other states, they can deny Trump the 270 votes.
Correct me if I’m wrong, but these democrat electors wanting to do this all appear to be from western/southwest states so far (WA, CA, CO)...they “claim” they want and would go for someone like a Kasich or Romney, but seems to me it’s actually a ploy to try to trick enough gop electors into going along with it to bring Trump’s electoral votes below Hillary’s, because what guarantee is there they would actually vote for another-Republican-not-Trump when it comes their time to vote?
Had these democrat electors been located in the Northeast/Eastern seaboard states which went abundantly for Hillary doing this and are the 1st ones in the nation to cast their electoral votes, it would appear a bit less sinister. But that they are in states which’ll cast their votes later indicates to me they wouldn’t hold their end of the bargain and vote for a “compromise” if this were to work and enough republicans abandoned Trump.
