Good for her
I’m frankly surprised that she did this. I can’t think of another GOP official who has done so. A tiny handful have said they won’t vote for Trump but I’ve not heard any but hardcore, unelected Never Trumpers say that you need to vote for Democrats instead.
I don’t know who she can influence but if there are a few McCain fans out there who recall his hatred for Trump (he was not even invited to the funeral, remember) maybe this will get them to vote for mark Kelly and Katie Hobbs, both of whom are straight arrow, mainstream politicians.
It shouldn’t take Liz Cheney saying this but partisanship is a helluva drug. It’s very hard to get people to just say no.
