I really don't get why the Romney bots are so insistent upon every one else conceding to "inevitability" if they truly think Mitt is a good candidate. A lengthy primary campaign most certainly did not hurt Obama in 2008. If anything, it helped him by enabling him to build up a tested campaign structure in many states for the fall instead of a few early ones. It also would give Romney's campaign a chance to try out different messages of why people should vote for Romney to see what is effective. He'll need more than mud being slung by his Super PAC come the general election.
In short, this needs to end soon because Gingrich is being so ugly that he's turning off a heck of a lot of female voters, who are going to decide who is the next POTUS (will definitely not be Gingrich, BTW).
