Take these with a grain of salt. I'm happy to predict broad trends but making specific predictions is not exactly my forte.
Nevertheless, I make the following predictions about the 2006 mid-term elections:
In the House, where all 435 representatives are up for election, I predict:
Thus the Democrats will control the House.
In the Senate, 33 Senators are up for election, I predict:
Which will give the following total in the Senate:
So after the 2006 elections, we will see both houses of congress controlled by the Democrats, but not so much that they can prevent a filibuster (60 senators) or easily impeach (67 senators).
Based on: My gut feeling.
