I think Linseed is done for. One of the lessons we have learned from the Bush years is to not fall for the line that we have to support RINO incumbents against conservative primary challengers, e.g., Spectre and Chafee. Get a conservative challenger in SC and GET RID of Grahamnesty in the primary, so we don’t have to choose between a skunk and a weasel.
You may need to support RINOs in a state like Maine, if they are good RINOs and follow the party leadership on key votes. They have to pretend to be liberal down the line in order to get elected.
But you sure as heck don’t need to support a RINO like Graham who actually has to pretend to be a conservative to get elected. You don’t need a RINO in a state where electing a reasonable conservative is possible.
