Eeeenteresting. As noted over at TPMDC, a new Quinnipiac poll has Arlen Specter in a dead heat with Pat Toomey, 45-44 percent. Against Joe Sestak, Specter’s Democratic primary challenger, Toomey’s up 39-35 percent; but both candidates lack real name recognition.

Specter now is roped to Obama’s economic policies; and the 2010 election will be seen, rightly, as a referendum on those policies. Toomey’s strength in the past has been with social conservatives, but my guess is he’ll be talking fiscal conservatism from here on in - he’d be foolish not to. Pennsylvania isn’t electing him on the basis of his stance against abortion. But he could get elected for standing against additional government spending.
