One big difference is that Arnold has the power to sway the GOP toward his liberal polices. Angelides doesn't.
So the question then becomes -- who's more harmful, RINOs or liberal Democrats? The answer, still, is the latter.
And therein lies the problem--and the dilemma. Arnold is awful and Angelides is more awful. I'm so sick of the media talking about "bipartisan" budgets and "bipartisan" bondage intitiatives, when the vast majority of Republican legislators opposed both. Now we have "bipartisan" global warming regulations, "bipartisan" land grabs, "bipartisan" GLBT "civil rights", all because the Governor (R) backs (or promotes) these things. Had the same things been promoted by Gray Davis instead of Arnold, they would have had unanimous opposition from the Republicans. Instead, we continue to lurch further and further to the left. Gridlock was a much better alternative than where we have headed with billions in deficits and borrowing.
