A Senate vote to repeal healthcare reform could come as early as this week, a senior Republican senator said Tuesday.

Any such vote would come on the heels of a federal judge's decision on Monday to strike down the whole law as unconstitutional.

Republicans, led by Minority Leader Mitch McConnellAddison (Mitch) Mitchell McConnellGOP strategist donates to Alabama Democrat McConnell names Senate GOP tax conferees Brent Budowsky: A plea to Alabama voters MORE (R-Ky.), have vowed to force a Senate vote to repeal healthcare reform. Sen. Jim DeMint (R-S.C.) introduced legislation mirroring the House's repeal bill, which passed through the lower chamber, and by Monday, all GOP senators had signed onto it as a co-sponsor, suggesting a united Republican front for repeal in the Senate.

But although McConnell has certain procedural tactics available to him, Democrats and Majority Leader Harry ReidHarry ReidBill O'Reilly: Politics helped kill Kate Steinle, Zarate just pulled the trigger Tax reform is nightmare Déjà vu for Puerto Rico Ex-Obama and Reid staffers: McConnell would pretend to be busy to avoid meeting with Obama MORE (D-Nev.) appear disinclined to allow a vote on repeal, even if it's likely to fall short of passage. Twenty-three Senate Democrats face reelection in 2012, some of them in conservative or swing states. Forcing them to take a vote for the record on repeal would almost certainly be used against them by the GOP in the 2012 elections.

It's not clear that Monday's court ruling will at all encourage Reid to allow a vote on repeal, though the politics have certainly engrossed the upper chamber.
