It’s going to be hard for other Democrats to replicate Obama’s coalition in 2014 and 2016. It’s not clear other Democrats can generate the turnout among blacks, Hispanics and young voters that he did.

And it’s pretty clear that under the Obama aegis, Democrats can not make the kind of gains in congressional races that they did in 2006 and 2008.

Back then Democratic strategists Rahm Emanuel and Charles Schumer fielded moderate-sounding candidates in Republican-leaning territory who were able to win because of discontent with the performance of George W. Bush. When his job approval fell below 40 percent, Republican candidates almost everywhere were hurt.

Democrats in 2014 will have to run as members of the party led by Barack Obama. That could be a hard sell in the 24 states and 228 congressional districts that he failed to carry in November.
