These data are from a Gallup poll conducted March 8-11, 2012. The 35% of Republicans who at this point say they would vote “enthusiastically” for Mitt Romney for president if he were to win the GOP nomination is identical to the 35% of Republicans who said the same about Romney back in late January/early February 2008.

In that same 2008 poll, however, 47% of Republicans said they would vote enthusiastically for John McCain, who ended up as that year’s GOP nominee. In short, Romney’s enthusiasm deficit in 2008 has carried over to his current campaign, with the difference being that none of the other nominees this year are generating any more enthusiasm among Republicans than Romney is.

Republicans are also less enthusiastic about voting for their party’s current pool of candidates than Democrats were about voting for their potential nominees in both 2008 and in 2004.
