A new Gallup survey finds that Democratic enthusiasm about voting in 2012 is about 22-points lower than it was in 2008.
That lower enthusiasm could translate to a lower turnout come November.
Republicans' greater enthusiasm about voting is a troubling sign for the Obama campaign, especially given the fact that registered voters are essentially tied in their presidential voting preferences and that Republicans historically vote at higher rates than Democrats do.
Lower Democratic enthusiasm at this point could also indicate that Democrats have not fully tuned in to the campaign, which is possible, given the lack of a Democratic nomination contest this year as there was on the Republican side. If that indeed is a factor, Democrats' enthusiasm may pick up steam in the fall after the Democratic convention. But if Democrats do not close the enthusiasm gap between now and Election Day, it would put Obama's re-election chances in serious jeopardy.
