Incumbent Senator Scott Brown may not make it to tonight's debate in Boston versus challenger Elizabeth Warren due to a scheduling conflict in Washington. 

Brown told the Boston Globe that if there are senate votes scheduled through the rest of the afternooon, he would have to miss the debate. 

"Voting is 'the one thing that I can’t delegate to the staff,' he told the Globe. 'I’ve only missed one vote.'

Brown told the Globe he would attempt to make a 4:30 p.m. plane so he could make it to WBZ studios by 7 p.m. for the flight. But he said his first priority is to vote.

“If we’ve got votes, I’ll make them,” Brown was quoted as saying. “I’m sure if we don’t make [the debate] tonight, we’ll reschedule it for Monday or something.”
