I agree the word, like “racism,” has been overused to the extent that it means little. But there are some who do deserve it such as McCain, Martinez, and Specter.
Agreed. Don’t know a lot about Martinez, but people like McCain who intentionally distinguish themselves from the party and obviously people like Specter who cross over to the Democratic side on key issues do deserve the title.
Mainstream Republicans who aren’t conservative enough (or in this case, conspiracy-theory oriented enough) for some here do not. Perhaps the Republican party as a whole can be criticized for its stance on these issues, but that’s a different issue.
