None of the other candidates were laying a glove on him, either on the campaign trail or in the two debates, and there was no reason for Romney to get away from his plan to be considered the de facto nominee and run against President Obama.
The Obama campaign managers returned the favor by making it clear they believed they would be running against Romney.
With Perry's entry into the race just over two weeks ago, Romney is no longer the front-runner, Michelle Bachmann has virtually disappeared from the news, and Tim Pawlenty has withdrawn.
None of this tells us what, if anything, will happen if Palin and/or Giuliani and/or former NY Governor George Pataki and/or others get into the race.
Nor does it tell us who will be standing on the stage in Tampa, Florida accepting the nomination of the Republican Party, exactly one year from now.
