Thanks, good reply. I get sick of the childish insults here (stupid, crude nicknames and sexual insults against a politician they dont like). It shuts down the real discussion, and also distracts from getting at the real reasons for somebodys behavior.
Personally, I think Graham just likes to be on the winning side. He has actually been pretty supportive of Trump lately, even though he didnt start that way. Its possible that Trump has actually earned his respect. Dont forget that Graham has been regularly reelected from a basically conservative but still heavily GOPe state, which means that his constituents appear to like him. And if hes beginning to like Trump, that means they do too.
And as you say, this statement coming from somebody who in the past was not known for being friendly to Trump means a lot more than having it come from the usual sources. Also, if Graham didnt think the power was on his side, he wouldnt have made the statement. So thats another good sign.
