And perhaps a U.S. Senate nominee. It seems likely that aging Senator James Inhofe will retire that year.
Inhofe's seat is next up in '08, not 2010. I'd imagine that the 'Rats would like to coalesce behind Congressman Dan Boren, who is one of the most Conservative Dems in the House (and is only 32). Boren's father and grandfather served in Congress (his dad's early retirement in 1994 allowed Inhofe to take the Senate seat when he did).
Frankly, I'd rather try to persuade Boren to switch parties (someone scoring in the mid 60s from the ACU really has no business serving as a Democrat these days). He previously worked as a staffer for another party-switcher, Wes Watkins.
