Momentum?

Citing recent polls, Human Events says the Santorum campaign has momentum.

Casey's lead has been slowly but steadily declining since November. Considering how little anyone actually seems to know about Casey and where he stands on any given issue, this should not come as a surprise as Election Day draws near and voters take a closer look at the candidates.

"Casey has equivocated or simply refused to articulate a comprehensive platform," says one GOP strategist. "All people really know is that his dad is [former governor] Bob Casey and that his campaign guys keep saying he's pro-life."

Especially in light of Bob Casey's recent proposal to expand childcare program of his father's.

What is odd to me is that people say "everyone knows he's prolife" and then there are polls that say otherwise.[1] [2]

Patrick Casey (no relation) also cautions...

[I]f Casey is depending on Bush to lose it for Santorum, he might want to consider a few things:

For one, it's hard to imagine Bush sinking much lower. At some point his approval rating is going to bottom out. When that happens, Casey is going to be forced to put some substance behind his name.

The Santorum camp has yet to air any of its own ads. As they frame the campaign and make the case for re-election, the impact of the President's poll numbers will decrease and fewer voters will use their vote as a referendum on the administration.

Also, at some point Casey will have to debate Santorum. Santorum is known for being quick on his feet and going toe to toe with him on policy issues is simply not something even optimistic Democrats think Casey can handle.

Finally, the Carpetbagger report adds...

There's little doubt that Bob Casey is leading in Pennsylvania's Senate race; the only question is by how much. While some recent polls showed Casey's leading slipping to the high-single digits, a new Rasmussen poll shows Casey ahead, 51% to 38%.

Momentum? Maybe. But the election is still half a year away.
