Whyizzit that any criticism of Bush and Republicans is never defended, but met with 'but the Democrats are worse.........' yada yackety quack. The Democrats have never pretended to be the party of smaller, less intrusive, low spending government. That claim always comes from Republicans. A look at their record makes them the hypocrites and makes a mockery of those who have supported them.
Your first bit is obvious baloney. Bush and the GOP are criticized for anything you could possibly imagine a few thousand things you're not looney enough to conceive of. Eg: Blowing up the Towers, creating AIDS, starting a senseless war in Iraq, stealing the Florida 2000 election, and on and on it goes. You'd have to be blind and deaf not to hear Repubs refuting these things right and left. Well, OK, mainly right. but anyway...
Are there a few dozen issues where "the Democrats are worse" is the only real response? Of course. We say that a lot, too.
And as for mockery, well, when a laughingstock laughs at others, it doesn't mean much.
