I've suspected for some time that the Bush administration is playing a very interesting game with regard to these U.S. Senate seats. Their primary concern isn't necessarily seniority, and it has nothing to do with incumbency -- it has everything to do with "ideological cleansing" in the Senate from both sides of the aisle.
To the Bush team, I'm convinced that the absolute worst thing for any state in the Northeast is a pair of U.S. Senators split between the two parties. In my opinion, the Bush administration would rather deal with two Democratic senators from a "Blue" state than deal with a Senator from each party -- because it's a lot easier to screw a Democratic state when it comes to Federal appropriations bills. This is exactly why the Bush administration did not lose much sleep when Jeffords jumped ship in 2001, and why they did not try very hard to defeat Lautenberg in New Jersey in 2002.
If Bush is serious in his support of Specter, it's because he thinks the odds of a Specter victory in November are better than the odds of a Toomey victory.
That's just my take on things.
That is quite a cogent bit of analysis! I'm impressed!
Now, can you explain to me Bush's attachment to Fox? That bends me all out of shape...
