Maybe the Republicans should have left the old guy (76 or something) alone and just let him "naturally" leave office. That way the party would have had some claim on the seat when it came to replace a Republican in office.
Republicans need to think...M..A..J..O..R..I..T..Y. Instead, they get mad and chase someone out when the guy will die in office in a few years. Was it really worth letting the D's get 60 votes?
Even here in Washington State there is too much infighting.
The Republican party would rather have more control over a small domain than less control over a larger domain.
