Over at HotAir, Ed Morrissey reads the tea leaves in the Rasmussen poll on Specter, Sestak . . . and an Arizona-style immigration bill:

Interestingly, Democrats still give Specter high marks — in fact, higher than Sestak.  Specter has an approval rating of 67% to Sestak’s 63%.  (Obama’s is 80% among likely Democratic primary voters.)  But voters perceive Snarlin’ Arlen as much more negative than positive on the campaign trail, 35%/22%, while Sestak is seen as more positive, 11%/39%.  Specter has a narrow edge among women, 47/40, but Sestak has a 24-point lead among men, 58/34.  Sestak also has overwhelming advantages among young voters, carrying the 18-29 demo 87/13, and in the 40/49 demo 54/24.  Specter only has a majority among thirtysomethings, 52/40, with the two splitting the other age demos.

Two other fascinating data points.  Among Democrats who favor repeal of ObamaCare, Sestak wins 59% of those who strongly favor repeal and 62% who somewhat favor repeal — as well as a 49% plurality of those who somewhat oppose repeal (Specter gets 38% of that demographic).  Specter gets 66% of the “not sure” votes, which just about sums up Specter’s career over the last thirteen months.

Lastly, this poll of likely Democratic voters show that they narrowly approve of an Arizona-like immigration enforcement law, 46/45.  That law looks more and more popular as it becomes more well known.
