So you're getting tired of Republicans in general?
Sorry, couldnt resist. You're in a system that THRIVES on pandering and you're complaining about it? If you're tired of getting wet, dont stand in the rain.
We call anti-tax people extreme because I dont really see a successful way to fund a government that we can live with that doesnt have anything to do with taxation. Any and every successful civilization and empire from the dawn of civilization to now has operated with the principle of taxation and I dont see any viable alternatives presented by any of the anti-tax people.
The entire movement are like broken records; they repeat "Lower taxes, less government" over and over but dont really seem to have any solid plans except take issues one-by-one. A reactionary movement is not noteworthy; anyone can be reactionary on their own.
As for O'Donnell, I find her interesting in the same way I find the drunk guy who just fell down three flights of stairs interesting; they provide a source of entertainment. Schadenfreude if you will. I dont think the witch comment made her un-electable, but it certainly didnt help her case any. If she was smart, she'd have dismissed it as a slight bout of verbal diarrhea with no real meaning and moved on. Instead, she took the rookie move and is dwelling on it, trying to explain it and rationalize it. Dumb move for any political figure.
The voting masses do NOT respond to logic, people are swayed more by emotion than logic. You can spend hours building a perfectly logical argument about something and have it smashed to pieces by someone wielding the baseball bat of an appeal to emotion.
