Ah, you've noticed that the Republicans are nastier and more aggressive/brash than ever. If Bush was your representative, you'd be on the defensive too. The destruction of the economy, the mockery of the constitution, eight years of corruption by corporate government, waterboarding and all means of torture, etc. is the Republican legacy (legacy of shame). The Republican conscience knows it has to be defensive because it is too prideful to admit they are responsible for letting the "American Dream" be destroyed.
Just think, after 8 years of Bush, Republicans still want to put Palin in the White House simply because she's a woman (it takes balls to be so unpatriotic and destructive) and trust the future of this country to someone simply because they are a woman.
