I tend to not really care how the already committed are going to vote, in terms of the broad electorate.
Last night was a matter of positioning to those voters who are not politically inclined outside of election month, who might not have a lot of political background to bring to the table (since if they did, they've likely been following things outside election season and already have an opinion). For those without any detailed knowledge to apply to their evaluation of the candidates, Romney positioned himself better. That's about all there is to say right now. I'm not sure why there are continual "yeah, but's"; it's not like those points are inaccurate, but they don't really have a bearing on who presented best to the uninformed voter.
