Red state Rats can’t ignore the voters this close to an election.
Here is what they fear:
1. People see the attack as an unfair smear on a good man.
2. Dims holding the letter for 2 months and only releasing it after the hearing is the type of dirty politics people hate.
3. the cry for special treatment as a condition to testify underscores the unfairness the dims want in the proceedings.
4. The dims had already turned the hearings into a circus.
5. That the effect of all of this will be to turn independents and some non insane dims off or take out their disgust on the dim candidate and REALLY, REALLY, motivate republicans to show up.
