I don't know about the ABS vote.
Sure, it might exist...heck I might be one of em...but it may not translate into votes for casey...
especially if there are strong Libertarian/Green candidates out there...
Thing is, Casey is essentially fighting Santorum on Casey's home turf...Socially Conservative Democrats...The conservative/uber partisan republicans will stay with rick...the partisan dems with casey, the liberals may (stress may) back a green while liberal moderate republicans (unless arlen can sway)...will likely stay at home...or vote Libertarian [some will vote casey...but I doubt they will in decisive numbers].
Casey has a lead...he should...that name is quite valuable...for it to be only 7 right now...before Santorum has moderated his image or thrown mudballs at Casey is something that should be observed carefully...as the battle will be waged on democratic turf.
Good analysis unfortunately for me. I know what the numbers say, but do you think us Dems would be better with a pro-choice, social liberal to rile up the base and invite out of state cash or bring back the conservative, pro-life Dems including those former Dems who are now GOP solely because of abortion?
