the evidence revealed in the Impeachment trial is so incredible that it can not be ignored, it is very possible that they will be pressured by conscience and/or their constituency to act.

"As a Christian, I believe that Separation of Church and State is Vital, not only for the People's Protection from an overzealous Theocratic Regime, but also for the protection of Religion from suppression."

Whether Bush and Cheney are impeached does not really matter to me. What matters is that they are prosecuted. It is quite evident that crimes were committed. The only thing impeachment would accomplish is the formal recognition of the disgraceful way they misgoverned this country. That's not what I want, and that's not what most Americans want. We already know they are a disgrace, we don't need the Senate to tell us. So I don't think we want them impeached or censured or made to stand in the corner with conical hats on their heads. We want them to pay. We want them held accountable — personally, legally, financially and historically accountable — so this kind of outrage won't likely be tried again any time soon. If they close out their lives in federal prison, that would be just about right.
I've read arguments on this site (and elsewhere) from both the rabid impeachment supporters and the timid anti-impeachment crowd, and I can't say that either is completely right. We can't just do nothing. Rome lost its republic when it did nothing to counter the actions of men who craved more power than had been constitutionally possible to amass. Do nothing and soon enough we will have a tyrant that makes Bush look like a pussycat. Yet impeachment has its problems too.
The thing about impeachment is that any attempt to pursue it would likely be met with opposition from some Republicans who would try to turn the proceedings into a political circus, levelling charges that the Democrats are interested only in settling past scores. The dilatory, grandstanding antics of a few Republicans would serve only to push any vote on articles of impeachment into late 2008, and as for a trial in the Senate — well, let's say the Senate hasn't proven itself able to cope with meeting tight deadlines lately.
So while I cannot advocate impeachment per se, that does not mean I wouldn't favor a Congressional investigation of the many mistakes, crimes and incompetencies that Bush-Cheney and Co. have committed. Au contraire. Such an investigation should be focused not to score political points or boost Democrats' re-election chances, but rather to buttress a federal indictment that would be filed against Bush, Cheney and the rest of the criminal conspiracy once they are out of office.
Using Congress' investigative and oversight powers to provide evidence for their eventual prosecution could be done in a way that would show people the Democrats were merely following the law and pursuing justice, not being vindictive for their own political gain. I think that the tone of such hearings would be about as important as any information gleaned from the investigation. If Democrats could refrain from gloating, casting aspersions or other triumphalist behavior and stick strictly to the impartial exposition of the facts, they might be amazed at how much Republican support they could garner for a post-election prosecution.
Done right, the investigation of the crimes committed by the Bush Administration would, I believe, lead to a modicum of national healing of the great divisions Messrs. Bush and Rove have engendered. A politically tinged witchhunt, though, leads only to more rancor and discord.
I come from Illinois where sometime next year, our former governor, George Ryan, will go to prison for his corrupt activities. The way that he was prosecuted (by a fellow Republican, as it happens) was that evidence steadily mounted up against him until NOT prosecuting him for his crimes would have been a greater crime in itself. The same thing can happen at the national level, and indeed it must happen if we are to enjoy a democratic (small d) future. That's why a premature and ill-advised impeachment procedure would not be in the country's best interests at this time, while the very same investigation (more thorough, one would hope, since the deadline is not as pressing) that would be part of any impeachment should be undertaken with dignity, impartiality and probity. Let's hope such an investigation begins immediately.

Welcome, Michael to Democrats.com!

Yes, investigations are warranted, and are preludes to impeachment. But I don't know where you're coming from, as you began by saying you didn't care about impeachment, only prosecution. But the two are linked. If you want to see some probable reasons, check Convict Bush and Cheney. Prosecution isn't precluded by impeachment.

And did you know that Bush is already planning his escape route?

All that South American partying that the girls are reported as doing isn't just fun. Daughter Jenna was in Paraguay finalizing a ranch purchase. You might wonder why Bush would choose Paraguay? Could be exceptions to its extradition treaty.

I guess my concern is if an investigation and then trial came for impeachment would the DLC members vote for impeachment or would they side with Bush like they have in the past?

I think Pelosi will crack under enough pressure from the public. So as soon as possible in January, we all need to contact our reps.
