Apologies for the Valley Girl-speak, but the term "Radical" might return to the political landscape if a Democrat gets elected in 2008.
I'm referring to the prospect of a Congress at odds with a president from its own party. This happened after the Civil War, when the struggle between Radical Republicans and Pres. Andrew Johnson led to the latter's impeachment. (The Radicals lost by one vote.)
I'm not saying that a "Radical" Democratic Congress irate over Iraq would impeach a President Obama, President (Hillary) Clinton, or President Edwards for not getting us out of there fast enough. The current Congress, after all, doesn't even seem to want to impeach anyone from the opposing party; look at how little support Dennis Kucinich is getting.
But it does seem like what Pat Buchanan predicted could come true with a Democratic victory in 2008: Iraq will split the party. Once dragged into supporting President Bush on Iraq, Congress is now led in the opposite direction by Speaker Pelosi, Senate Majority Leader Reid, and the conscience of the Capitol, Rep. Jack Murtha.
A possibility exists that could guarantee gridlock when a Democrat steps into the Oval Office: an anti-war Congress arguing with a president who either voted for the war as a senator (Clinton, Edwards) or who said in John Kerry style "that while he would have voted against the war in 2002 based on what he knew at the time, he could not be sure that classified intelligence reporters made available to senators wouldn't have changed his mind" (which the Boston Globe describes Obama as frequently saying).
Should Clinton, Edwards, or Obama win in 2008, they will need all the political talent of an Abraham Lincoln to escape this scenario.
