Obama's biggest accomplishment

It just hit me what Barack Obama's biggest accomplishment was this week.

Let's look at the last three Democratic presidential wins. When Clinton won in 1992 and 1996, Republicans could blame Perot. When Carter won in 1976, Republicans could blame the long-departed Nixon.

Obama's win was the first time since 1964 that the Republicans have lost the White House without having any plausible excuse for it. The GOP was flat-out, straight-up beaten. Many prominent Republicans have never experienced that before, which might explain the shock we've been seeing.
