Defeating Brown makes the goal of "enough new Republicans" 1 seat more difficult. Personally, I'd take a 74% friend over a 0% friend any day of the week. And in Mass, you are not going to get any better.
Fat lot of good when the 26% votes go to the opposition on the big critical votes.
Voting percentages are meaningless without an issue by issue analysis.
In Montgomery Co. Maryland we had Rep Connie Morella who crossed the aisle so many times my cohort of conservative friends called Connie the Red, and not just because of her fondness for red jackets.
Remember when many of us donated to that turncoat SOB and the minute he won, the dewy eyed here made him the flavor of the month as a presidential candidate?
Screw him - not one dime of out of state support. Send ducats to real conservatives in battleground states.
