Massachusetts:
Barack Obama 62%
John McCain 36%
...And yet Scott Brown won just a year later. While I grant you that Brown is more liberal than O’Donnell obviously (especially on many social issues), he campaigned as a candidate decidedly more conservative than Castle.
Further, Brown ran as the 41st vote against Obamacare; now that Obamacare is even more unpopular than it was then, why is Castle saying that he won’t vote in favor of repealing it if he’s Senator?
