I hate to be a bearer of bad news, but the 2006 midterms aren't going to be the panacaea that many around here seem to think they are. In fact, I'm not completely convinced that they're going to help one bit.
Let's start with the obvious: Even if you accept that this President has committed "high crimes", it's doubtful that there would be enough Republican members of the House and Senate that would be willing to call him out on it to even begin impeachment proceedings. If things get really desperate, I wouldn't be surprised if impeachment proceedings are begun simply to exonerate the President -- "Look, we had hearings, and we all agreed that the President did what he had to. Stop whining."
Okay, so in that case the Dems need to increase their presence in at least the House. Which isn't going to happen before 2006 (er, January 2007). Say by some miracle (the general public wakes up?) the Dems take back both the House and the Senate, and impeachment proceedings begin right away. It's important to remember our history: Watergate took fifteen months between opening the hearings and Nixon resigning; The Lewinsky scandal took over four years from the start of the Whitewater hearings until the House impeached Clinton. It's unlikely, therefore, that Dubya will be removed before the middle of '08 -- and even if he is, we'd then have either Halliburton or Hastert taking his place. Is that any better?
All of this, of course, assumes that the President -- who effectively controls the military, remember -- doesn't decide that, since we're at war and he's got unlimited power, why not suspend the vote? After all, it would be in the country's best interest for him to remain in power until the "war" is over, right? Can't leave it up to those mamby-pamby weak-on-security Dems, or even worse the general public that's been lied to so long by the librul media they might not understand the holy righteousness of Dubya's crusade.
No, I'm afraid our best chance of cleaning up this mess is to remind Republicans in the House and Senate that, once upon a time, they were wary of the expansion of the government's powers. They fought tooth and nail for a strict reading of the Constitution and Bill of Rights, in particular the 4th Amendment. It's up to Repblicans to repudiate the President's power grab and remind him that we're a country of laws -- and unless they do that right here, right now, this country is in danger of becoming that which they claim they're saving the Iraqis from.
Good luck to all of us. We'll need it.
