yes, but still, this can't be ignored. I don't believe this is just some "trial balloon", the left is going to run with this as a coordinated effort. remember, the left doesn't look at a poll and say "no way the american people are going to support impeachment of Bush". they look at it and say - "hey, if we can pump enough disinformation and convince X% of the sheeple of this, we can make a move here".
I agree it can't just be ignored. The only way it will happen is if the Republicans don't stand up for him and lay out the facts in press conferences, etc. We have to make phone calls and be activists or the spineless Republicans won't take it seriously.
