A friend posted on social media a link to a social media article labeled "Lindsay Graham says he won't read impeachment transcripts," and he has also full-throatedly supported Tr*mp in other forums. Another friend asked, "what happened to him? John McCain must be turning over in his grave."
It seems rather obvious: He's positioning himself as Tr*mp's successor, knowing he'd whomp VP Mike Pence in primaries. By appearing to support Tr*mp now, he can preserve rapport with the crazies while potentially appealing to a wider audience.
Would a deposed Tr*mp support Pence or Graham?
