So he's buying off the market he's more likely to win anyway? Romney needs to campaign in swingy counties like Lehigh and Lancaster (which, being on the ground, I think will be close), not Chester and Montgomery.
Nothing seems to turn on the statewide vote, so it is all about picking off individual CD's when it comes to delegates. And probably there are more swing voters outside western, PA then inside anyway. As a wild guess, the Lehigh Valley and the York/Harrisburg area are homes to the closest CD's.
All the camps seem to be keeping who "their" delegates are pretty much under wraps---or if there is an effort being made, it's really local or rather clandestine.
For the Romney camp...it doesn't really matter. Presumably, a large number of the delegates (who really just want to go to Tampa / add to their resume, rather than support a particular candidate) are presumably going to come around to Romney sooner or later. If people pick delegates based on name recognition alone, they're likely voting for someone who will eventually vote for Romney.
For the Santorum camp...Santorum doesn't exactly have full 'slates' of delegates anywhere, which is really just embarassing.
For the Paul camp...having the Paul delegates be public knowledge likely hurts their chances of getting delegates by chance.
And nobody cares about Gingrich.
The "but it's about the delegates!" story will be some nice spin from the Romney camp if he loses---but the odds are we won't know even where half of the elected delegates' loyalties lie the day after.
