When the Democratic leadership of Congress decided to back off from their demand for a timetable of withdrawal in the latest draft of the Iraq funding bill they created a problem for two of the Democratic front-runners and an opportunity for the third.
The candidates with a problem are Hillary Clinton and Barack Obama. The candidate with an opportunity is John Edwards. Clinton and Obama are serving U.S. Senators and must vote on the proposed funding bill. John Edwards is no longer a serving Senator and doesn't have to vote.
