Rep. Joe Sestak (D-Pa.) may have found his wedge issue in the race to usurp the Democratic nod from Sen. Arlen Specter (D-Pa.), establishment Republicans continue their embrace of Nevada Senate candidate Sue Lowden and New York Gov. David Paterson (D) didn't get his invite to President Obama's Buffalo rally.

'I actually voted against her before I voted for her'

The pending announcement of Solicitor General Elena Kagan's appointment to the Supreme Court will likely prompt a new line of attack in the Pennsylvania Democratic Senate primary. Specter voted against confirming Kagan as solicitor general in March of last year. He was a Republican at the time and Sestak will surely want to remind Democratic primary voters of his decision.

Recent polls have shown Sestak edging ahead of Specter with just over a week before the Democratic primary.

Kyl: Chickens are just a 'distraction'

Sen. Jon Kyl (R-Ariz) pushed back against the suggestion Washington Republicans were worried about Sue Lowden’s Senate candidacy during a Las Vegas fundraiser for her campaign Saturday.

"Heavens no," Kyl said when asked if the GOP was worried about the “chickens for checkups” controversy. "That's a distraction and I think people realize that is not her plan for health care. She was discussing a historical reality. But she was not saying it's part of her health care plan."

Without mentioning Senate Majority Leader Harry Reid (Nev.) by name, Kyl added, “that is the kind of distraction an opponent who doesn't have much to talk about will frequently create." 

Kyl said he and Lowden have much in common. "Her views and mine are quite close," he told the Las Review-Journal. "And she's very electable."

Must've gotten lost in the mail

President Obama will be in Buffalo May 13 for a rally in support of Sen. Kirsten Gillibrand (D-N.Y.).

Attorney General Andrew Cuomo (D), who's expected to run for governor, is also set to attend, according to reports. New York's current governor, however, isn't sure if he got an invite.

"I actually don't know that. I know he's coming, and I'd have to get back to you on that," David Paterson told a Buffalo radio station. "It's just not something that I happen to know off the top of my head."

Asked about the White House's attempt to discourage him from running for a full term, Paterson sounded sanguine. 

"I didn't feel snubbed, and I said it at the time," he said. "People read all kinds of things into anything, and I think the president has got a lot of things to deal with on a macro level like what we’ve got in New York State."
