The midterms: McCain and immigration

ARIZONA: The AP writes, "Republican Sen. John McCain, who once championed a path to citizenship for the nation's roughly 12 million undocumented immigrants, is now pushing for a crackdown on illegals amid the toughest re-election fight of his career. McCain's hardline stance on immigration comes in the face of a credible GOP primary challenger, former Rep. J.D. Hayworth, and the possibility that the party's 2008 presidential nominee could lose his Senate seat because many conservatives don't consider him one of their own. Engaged in a fierce contest with the tea party-backed Hayworth, McCain has moved to the right on numerous issues, including gay rights and climate change, and disavowed his long-standing maverick label."

FLORIDA: "If he chooses to run as an independent, [Gov. Charlie] Crist would be betting that the prevailing political logic of the moment is wrong -- that despite the Tea Party's rise, the broader electorate still wants the pragmatic approach that propelled Barack Obama to victory here," the New York Times writes.

KENTUCKY: "Republican Rand Paul held his fifth and, his campaign said, final online 'money bomb' fundraiser, bringing in more than $101,000 in 24 hours," Roll Call reports. "Although breaking six figures, the fundraiser brought in quite a bit less than similar events staged by Paul's campaign to win the GOP Senate nomination. … As of April 1, Grayson had more than $1 million in the bank compared with nearly $400,000 banked by Paul's campaign."

MINNESOTA: Roll Call jumps into MN-6, Michele Bachmann's seat.

NEW HAMPSHIRE: Gov. John Lynch launches the first campaign ad in his re-election campaign, WMUR reports.

PENNSYLVANIA: "U.S. Vice President Joe Biden will headline the rally Friday for U.S. Sen. Arlen Specter at the Wilkes-Barre/Scranton International Airport, according to a news release from Citizens for Arlen Specter. The rally will be in Hanger No. 1, with the doors open at 12:30 p.m. and the rally beginning at 2 p.m."

WEST VIRGINIA: "Rep. Alan Mollohan (D) is airing a campaign commercial that attacks state Sen. Mike Oliverio, his opponent in the May 11 Democratic primary, for his ties to a conservative-leaning organization of state legislators," Roll Call writes. "The ad, which began airing Tuesday, responds to an Oliverio spot that criticized Mollohan's ethics." Ethics was a top issue used against Mollohan in 2006, but he was able to survive because of the national Democratic wave.
