A Wilson candidacy could prove to be a great twofer for Democrats: her involvement in the US Attorney scandal provides plenty of baggage to damage her Senate chances, and she leaves behind yet another open House seat ripe for the picking (at a PVI of D+2.4, Kerry won the district by three points in 2004).
Let the games begin.
New Mexico's two other House members, Democrat Tom Udall and Republican Steve Pearce, both were said to be mulling bids for the Senate race.
Democratic Rep. Mark Udall of Colorado said his cousin, Tom Udall, has "been planning for this moment," but noted that Richardson remains a key player in the process. Udall was not expected to announce anything Thursday.
Pearce said he wanted to wait "a respectful time" before making a decision. "We should not be jockeying for position, kicking him out the door," he said.
In a statement, Richardson said Domenici had been a "respected and powerful champion for New Mexico's interests" for more than three decades. Tom Reynolds, a spokesman for his presidential campaign, said Richardson remained "100 percent committed to winning the White House."
Democratic Lt. Gov. Denise Denish, who has been gearing up to run for governor in 2010 when Richardson would be term-limited out of office, said she would consider the Senate race.
"This reshuffles the whole deck in New Mexico," she said of Domenici's retirement.
"I've been very focused on running for governor and that's still where my focus is right now, but I think in fairness I need to listen to some people that are talking to me about the possibility of running for this Senate seat and see what they have to say and see what the possibilities are," she added.
Former New Mexico Attorney General Patricia Madrid also said she was considering a bid for the seat. Madrid lost the 2006 election against Wilson for the 1st Congressional District by fewer than 900 points, and said she expected she would perform better in a statewide contest. "I think that I could run a very credible race," she said.
