Allahpundit is a pragmatist -- O'Donnell can't win the general election, therefore voting for Castle assures a Republican victory. This is based on two assumptions in a season of destroyed assumptions. There's a good chance that the Tea Party is not the major force behind the rise of O'Donnell, and as odd as it seems, Delaware voters might be tired of economic stagnation and a too-powerful government.
When I look at the two candidates, and even past the esthetics, O'Donnell appears to be the much better choice. Castle is representative of everythig wrong with government -- insider, deal-maker, Republican statist, out of touch, dishonest, just a died-in-the-wool professional politican with no vision of a free market and free society. O'Donnell is fresh, energetic, independent, believes in a free market and has a vision of growth and prosperity generated by an empowered private sector.
In any revolutionary change, people have to step forward, take chances, be diligent, stick to principles and expect the impossible. I probably disagree with many of O'Donnell's social positions, but this election is about limited government and a free market, not whether congress will attack Roe v. Wade and gays -- that's not going to happen. Conservatives have accepted social changes and bring up social issues as a point of agreement, not a platform for legislation. As far as the wars go, the public will take care of that soon as they turn against the continuance of two wars which are unraveling in the nation-building stages, so, whatever O'Donnell thinks about the wars, public opinion will determine that outcome.
Anyone who supports a Castle win should switch parties, but, it's not just the senate race in Delaware, it's about the overall strategy. A Republican victory in the House, which is the short-sighted, limited goal, accomplished by supporting statist, status quo Republicans, is a victory for the Democrats given the Dems should lose the House and the Senate to limited government conservatives if the nation is serious about repealing the power-grab. If Republicans gain only the House with statist/establishment Republicans, the nation is not yet serious about a free market or limited government.
