Your point that, from our perspective, this election is about preventing the Democrats from totally consolidating power is absolutely correct.
We stand to lose 3 to 7 Senators. With such losses, I don’t believe we would be able to sustain a filibuster in the Senate (think of the several RINOs in our midst). With a majority of any size in the House, a large enough majority in the Senate to overcome a filibuster, and the White House, it will be Katy Bar the Door.
On the other hand, with a RINO president, and a firmly Democratic Congress, the net movement will be in the wrong direction, but we will survive.
Hopefully, in 2010 and ‘12, and with the War in Iraq finally over, we’ll retake the House and the Senate.
This is why I would support McCain enthusiastically as long as he names a conservative running mate. I am looking toward the future.
On the other hand, if he names a fellow RINO, I will give serious consideration to supporting Bob Barr.
While I'm also pessimistic, there is one thing that gives me some hope: the blue dogs. They are the ones who killed Amnesty. I also think they can be relied upon to kill some of the worst Dem excesses in the tax and spend area. So even if we lose some Senate seats, it won't be as bad as some are predicting.
