This year is different. There is an anger at politics as usual and the voters have woken up to it.
I think a lot of people misread the Tea Party, Town Hall anger as pro-Republican but it is not. It is anti business-as-usual in Wash DC and business-as-usual is the first and foremost MO of the democrat.
Consider this: Why, when the democrats had their super-majority, couldn't they just vote straight up and down on all of Obama’s agenda? Why all the wheeling and dealing, the behind closed door promises, the pork barreling and flip-flops? This is what people are pissed off at! It isn't anti-democrat or pro-republican. To think so is a misread of what will happen in November. This anger will be not only directed against the democrats, but against RINOs, too.
To that end, Christine O'Donnell is the main benefactor in Delaware of that mood. This mood has clearly manifested itself in many primaries (although John McCain overcame it), and will be a huge factor in November.
And believe it or not -
Christine was a staunch Conservative BEFORE the TEA Party Movement got going.
