It's not likely, but it seems possible that Obama could be impeached for the Libya war.
There's clearly a case to be made for it. But of course, that is not why the Republican establishment would do it.
Both House Speaker John Boehner (R-Ohio) and Rep. Dennis Kucinich (D-Ohio) are talking about putting forward a vote to cut off funding for war in Libya. If that vote passes, and if Obama continues the war in Libya, then the House could look like a defunct body if it doesn't pursue impeachment.
Pursuing an impeachment of Obama may be in the interest of most political players:
* The establishment Republicans, especially in the House, who want to get the enthusiastic support of the Tea Party crowd would pose as great defenders of the Constitution.
* Republicans committed to a militarized foreign policy like John McCain would pose as "grownups" who are acting in the "national interest" by voting against conviction in the Senate.
* Any impeachment effort, even if successful in the House, would almost definitely not result in conviction in the Democratic-majority Senate, so it wouldn't may not actually change a great or threaten the militarized foreign policy establishment. That is, the war would likely continue.
* Hypocrites could endlessly decry each other's hypocrisies: Democratic partisan hacks talking about Bush's wars and Republican partisan hacks talking about how Obama didn't get any kind of Congressional approval (as Bush got for the Afghanistan and Iraq wars) could work to solidify their bases by endlessly attacking each other. A largely partisan affair could insulate future presidents from undergoing such impeachment.
* This would give Obama and other establishment Democrats further fuel to tell their alleged base how horrible Republicans are and help further cover for their lack of providing them with anything approaching tangibles positive change. Like Clinton before him, Obama could play the victim. Instead of him defending his alleged base, they would be called upon to defend him in what is ultimately an unconstitutional act. (Clinton's poll numbers actually went up as he was being impeached.)
* The silver-lining here is that principled opponents of militarism and empire -- coming from both the left and right -- might be able to articulate their positions and move toward a meaningfully democratic foreign policy, but the establishment media will simply highlight the establishment partisan bickering.
* At a minimum -- especially if Obama is not interested in getting impeached -- the prospect of impeachment gives the House Republicans leverage on various other issues, such as the debt debate and Medicare, Medicaid and Social Security. Obama's subservience to a militarized foreign policy will therefore have multiple costs. Should such deals be struck, it will be an instance of Husseini's first law of politics: The powers collude and the people get screwed -- and not in a good way.
