It's all about money right now. Hillary may run for reelection in 06. She may run for Prez in 08 and still retain her seat if she loses. This move did not hurt her in NY, and 4 years is a long time for voters to forget.
If Hillary wants to win in 2008 she needs money. Lots and lots and lots of money...to win re-election in the Senate, the presidential primaries, and the general election. I would need to use a lifeline - phone a friend to find out for sure, but I believe Hillary can raise money as a Senator from NY and use it to run for President. Tomorrow the direct mail from Sen Clinton goes out to President Clinton's donor list.
Hill has enough connections that money will not be an issue, especially if Terry remains Chair.
Again, the base will be with her (including N.Y.) if they believe she can win the "moderates". Those same people she needs to win would not be impressed by her actions in the Senate yesterday. And, people will be reminded of it. She's on Tape. It was a foolish move on her part.
