With Sen. Ben Nighthorse Campbell (R-Colo.) out of the race, the battle over which party controls the Senate is drawing speculation over who will seek the open seat.

Some Democrats and Republicans say Gov. Bill Owens, a Republican might run. Owens has two more years left in his second and final term.

Several Republicans said they were considering a campaign, including Reps. Tom Tancredo, Bob Beauprez, Marilyn Musgrave and Scott McInnis. On the Democrat side, Rep. Mark Udall is said to be mulling a run.

The Senate is currently split 51 to 48 in favor of Republicans. If a Democrat is elected to the White House, the Democrats would need a net change of one seat to gain control. If President Bush is re-elected, they would need two seats.
