Harry Reid has scheduled a vote immediately following Obama's speech tonight, and it's not one many Republicans will want to miss. As soon as Obama is done talking, the Senate will take up a measure disapproving of the $500 billion increase in the debt limit.
The vote to disapprove of the debt ceiling increase was negotiated in debt-ceiling deal cut this summer. The measure gives Republicans a chance to vote against raising the nation's borrowing limit, though ultimately it will be impossible to stop. Even if the disapproval measure passes both chambers, Obama will veto it and Republicans do not have enough votes in the Senate to override him.
