In New Hampshire, two Democrats are already vying for position to unseat Senator John Sununu. Democratic activist Katrina Swett (who challenged Republican Charlie Bass in '02) has already filed papers for a run, and Portsmouth Mayor Steve Marchand will follow suit shortly.

Both candidates are keeping an eye on the 800-lb gorilla currently standing on the sideline: Jeanne Shaheen. The popular three-term Governor who lost to Sununu in a close race six years ago hasn't officially ruled out a rematch. A run by Shaheen would most likely clear the Dem field and make for an exceedingly difficult reelection battle for Sununu.

Out in Colorado, Dems are already jockeying for position to replace Rep. Mark Udall in the 2nd Congressional district who is making noise about a 2008 Senate run. Prospective candidates include State Senate President Joan Fitz- Gerald and millionaire philanthropist Jared Polis.
