In the 2004 election, Karl Rove masterfully used gay marriage as the catalyst to drive normally apathetic voters to the polls and achieve historic turnout. It worked. Republicans of all ages, shapes and sizes who couldn't care less about manufactured WMD intelligence, record deficits and gas/oil prices, CIA leaks and warrantless wiretappings raced to polling places across America just to keep homosexuals from tying the knot.

Well, the Democrats have an even better weapon this year: impeachment. If they're smart, they'll make it the linchpin turnout strategy and the single biggest motivator for liberal voters. To be sure, it'll be hard for individual candidates to make this message the cornerstone of their campaigns. They'll need to run on more than that if they want to be taken seriously. But the impeachment issue could be our Swift Boat weapon. Organizations like MoveOn.org, as well as individuals like billionaire George Soros who heavily back such groups, should pull out all stops and launch a massive campaign. I can hear the 30-second spot now:

"President Bush has lied about WMD and caused a deadly war. He's lied about the connections between Saddam and Al Qaeda; about Uranium in Niger. He's lied to us about the war's true cost and its progress; about nation-building; about torturing prisoners. He's lied to us about the true cost of health care; about Social Security's solvency. He's broken the law with warrantless wiretappings. Isn't it time to stop George Bush from lying and breaking the law? Isn't it time Democrats take back control of the House and impeach George Bush? You can make this a reality. Make sure you vote next November."

A very effective message indeed. Howard Dean, Rahm Emanuel, are you listening?
