I have thought for a while that Carson and Huckabee would support/endorse Trump, too.
He’ll be in OK, I think Gov Mary Fallin is fairly well respected there (don’t know for sure, just from what I’ve read) - might be cool if she endorsed him, but maybe she isn’t endorsing anyone right now, I don’t know and am just throwing it out there. There’s also Imhofe an Coburn.
I saw Fallin interviewed yesterday and got the feeling that she’s leaning toward Trump. It’s Oklahoma and they’re patriots and evangelical.
