Cassidy vs Landrieu: How will their fiscal cliff votes affect the 2014 Louisiana Senate race?

So, Sen. Mary Landrieu voted for the fiscal cliff deal in the Senate. Her likely Republican opponent, Baton Rouge Congressman Bill Cassidy, did not.

Northeast Louisiana Rep. Rodney Alexander, a Republican, and New Orleans-Baton Rouge Rep. Cedric Richmond, a Democrat, were the only Louisiana members to support the bipartisan deal in the House.

But it's the votes of Landrieu and Cassidy that are the most interesting because the fiscal cliff could be an issue in the 2014 Senate race and influence Landrieu's re-election bid.
