The Wave

The dimensions of this, summarized by kos:

We won, and won big. Not only did we take the Senate, take the House, and destroyed Republicans at the state legislative level, but we didn't lose a single senate seat, we didn't lose any House seats, we didn't lose any governorships, we didn't lose any state legislatures. It was a rout of epic proportions.

Kos is also trenchant on the Democrats' agenda, and shoots down the notion that the Democrats elected were conservatives. While some have different positions on social issues (most of which they'll never have to vote on), they are much more progressive and populist on economic issues, against the war and torture, and for constitutional rights. In other words, they aren't extreme right wing lunatics, like the ones who have been running the country. Matt Stoller has more specific details on Dem candidates--the more conservative tended to lose, while the more progressive won. Note especially the support for universal health care.

Georgia10 adds this: When you can't get an abortion ban passed in freakin' South Dakota, America isn't trending conservative. When you can't get a gay marriage ban passed in Arizona, America isn't trending conservative. When opposition to gay marriage bans was more than 40% in 5 of the 8 bans that passed, America isn't trending conservative. When a majority of Americans choose Democrats to represent them, America isn't trending conservative.

Apart from the governator, the Wave swept Democrats into state offices in California. Results on propositions are mixed, but the worst ones were defeated.

Think Progress outlines some of the "firsts" in this tidal wave: the first woman and first Italian American Speaker of the House, more women in the Senate than ever before, the first Muslim elected to Congress, three House committees with African-American chairs, and of course (though TP doesn't mention him) Senator Bernie Sanders, the first declare socialist, who is so down to earth that his socialism is not an issue in Vermont or probably anywhere else.

The first victim of the wave was Rumsfeld, who promptly quit as secretary of Defense. But Bush promptly appointed an insider cut from the same cloth, who may go along with a change in policy but is an interventionist and Republican loyalist deeply involved in Iran-Contra and past machinations that helped create enemies in the Middle East and elsewhere. It seems Bush really wanted to appoint Kissinger, but even the lame duck Senate might not confirm a zombie.
