A: Because he’s not worth impeaching.
For which Harry Reid’s Senate wouldn’t convict.
And, we don’t want to hand the Left a martyr.
Obama is worth impeaching; however, as you said, we won't get a conviction with that other slime, Harry Reid, heading up the Senate. Maybe the Senate in 2014 will have the cojones to convict the phony messiah.
We didn't do that when we impeached Slick. He beat the impeachment and stayed in office, but the black mark was wider and blacker than a set of street slicks would leave, and no matter what the Left does, it'll never, ever wash off. It's historic.
