I figure a Republican majority in the House of three-to-five seats, and the Senate not so different from what it is now, except for the loss of Lincoln Chafee's seat.

To be honest, I'm not even sure Chafee will lose, but he ought to. This is beyond partisanship: If only 100 citizens from a population of 300 million get to be senators, Lincoln Chafee should not be among them. On the other hand, if Rick Santorum loses, he will nevertheless emerge from this election with a reputation more enhanced than the winner — and, for the party, the loss of the Pennsylvania seat will be offset by gains elsewhere, either in Maryland or Washington State. In the House, I think both the Foley and DeLay seats will be retained.
