This Jim Geraghty piece up on NRO, in which he he interviews longtime GOP insider “Obi Wan” about the coming election, is well worth a read.
This is the quote I found most striking:
“There are no moderate Democrats in Congress, because when you vote for a supposed Blue Dog you are voting for the enablers-the ones who keep the House and Senate run by liberals”
For much the same reason there’s no such thing as a pro-gun Democrat.
I have a hard time thinking of Blue Dog Democrats as “moderates”. They’re merely stealth Republicans.
