I think they're well aware of the message a "not voting" would send about their commitment to the War on Terror. It's as good as a "no" -- and people WILL notice.
Not voting will save them somewhat from the American public, but would get scorn from their far left DUers types.
Voting NO gets their DUers happy, but will get most of them unseated in 2006 & 2008.
So look for the far left to be pissed off with lots of non-votes.
Can you see comericals now?
At one of the most important votes in our nation's history my opponent voted no or didn't show up. If I am elected your congressman I vow to take our nations security seriously.
