Sink, Florida’s Chief Financial Officer, looks like she will have a clear path to the Democratic nomination, and is likely to face Republican state Attorney General Bill McCollum, a former 10-term House member who was the GOP’s U.S. Senate nominee in 2000 and a candidate in the 2004 Senate primary, in the general election. CQ Politics rates the race a Toss-Up.

Denish has served as New Mexico’s lieutenant governor during two terms under Democratic Gov. Bill Richardson and was previously the chair of the Democratic Party of New Mexico. She is the early favorite to succeed Richardson, who is term-limited, in 2010, though she is likely to face a contested primary and general election to get there. State Senate Majority Leader Michael Sanchez is exploring a Democratic bid and a handful of Republicans — Albuquerque financial adviser and Army National Guard brigadier general Greg Zanetti, former state Republican chairman and Albuquerque businessman Allen Weh, State Rep. Janice Arnold-Jones and former Congress members Steve Pearce and Heather Wilson are all declared or considering run. CQ rates the race Democrat Favored.
