DELAWARE: “Republican stalwart Mike Castle’s unbroken run of election victories ended abruptly Tuesday, thrown off track by a flash of conservative voter anger and a flood of political rhetoric poisonous to anyone in the middle,” the Wilmington News-Journal writes.

The Boston Globe's lead: "The surging Tea Party movement grabbed a startling upset last night in Delaware, defeating a longtime politician who had the backing of the Republican Party establishment and delivering a blow to the GOP’s hopes of recapturing the Senate majority."

The Hill's headline: "Tea Party win strikes blow to GOP hopes of winning Senate in Nov."

Former President Bill Clinton at an event for former Sen. Mark Dayton, running for governor of Minnesota, reacted to the Tea Party wins and compared the GOP now to Bush: "A lot of their candidates today, they make him look like a liberal."

Politico notes the "very short" NRSC statement on O'Donnell’s win. The statement, from NRSC executive director Rob Jesmer, in full was all of 17 words: "We congratulate Christine O’Donnell for her nomination this evening after a hard-fought primary campaign in Delaware.”

Christine O'Donnell won last night with just 29,882 votes. While Delaware is a small state, consider that in Tom Carper's 2006 win, he got more than 170,000 votes. The losing opponent, Republican Jan Ting, who only got 29% of the vote, garnered almost 70,000 votes. In her 2008 65%-35% loss to Biden, O'Donnell got about 141,000 votes.

Democrats also happy that in the House race they hope to flip in that state, Republicans appear to have gotten their most conservative candidate -- Glen Urquhart, who leads with 99% reporting by just 48.6%-47.7%, or 552 votes. Full Delaware election results here.

DC: “D.C. Council Chairman Vincent C. Gray won the Democratic nomination for mayor, as voters rejected incumbent Adrian M. Fenty's hard-charging style in favor of promises of a new, conciliatory approach to governing a fast-changing city,” the Washington Post writes. “Tuesday's vote marked only the third time in District history that D.C. residents have ousted a sitting mayor.”

MASSACHUSETTS: Scott Brown-endorsed "State Representative Jeffrey D. Perry, a Cape Cod Republican who captured the conservative wing of his party, handily won the GOP nomination last night for the open 10th District congressional seat and will face Democrat William R. Keating, the Norfolk district attorney, following a state primary election yesterday that offered hints of GOP enthusiasm up and down the ticket."

In MA-9: "In the state’s only serious Democratic contest in US House races, incumbent Stephen F. Lynch, a Democrat from South Boston, easily defeated challenger Mac D’Alessandro, a union organizer who sought to tap into liberal anger over Lynch’s opposition to President Obama’s health care plan and his earlier support for the Iraq war."

NEW HAMPSHIRE: The New Hampshire Union Leader: There are 44 precincts still out, but with 85% reporting, Kelly "Ayotte held a slight lead -- close enough for Lamontagne to legally request a recount if the margin held -- with 257 of 301 precincts reporting. Ayotte had 46,331 votes while Lamontagne had 45,352, the AP reported." More: "If Lamontagne is able to complete the victory, it will be his second insurgent win over an establishment front-runner in his political career. Fourteen years ago, he upset then-U.S. Rep. Bill Zeliff in a gubernatorial primary only to lose to Democrat Jeanne Shaheen in the general election." And: Lamontagne "spent only about $500,000, about one-quarter of Ayotte's total and far less than Binnie's $6 million personal investment."

So why the delay? The Concord Monitor: "Several town clerks have told us they're laboring to comply with new reporting requirements from the secretary of state's office. Those requirements stem from a federal mandate regarding the timely availability of general election absentee ballots. The window of time between today's primary and the November election is about as tight as allowed under the federal rules."

NEW YORK: “Carl P. Paladino, a Buffalo multimillionaire who jolted the Republican Party with his bluster and belligerence, rode a wave of disgust with Albany to the nomination for governor of New York on Tuesday, toppling Rick A. Lazio, a former congressman who earned establishment support but inspired little popular enthusiasm,” the New York Times writes.

Describing Carl Paladino as a "wackadoo," The New York Daily News' Hammond writes, "Paladino loves to bluster about going after Albany's powerbrokers with a baseball bat, but the only thing he's likely to beat to a pulp is the state GOP's credibility. Or what's left of it, anyway."

The Daily News writes that Charlie Rangel may have won, but his margin was smaller than he'd hoped for. After all, almost as many people didn't vote for Rangel as voted for him.

The New York Post: Paladino's "campaign began with a series of embarrassing revelations that could easily have torpedoed his bid. He was caught forwarding racist and dirty e-mails, and referred to Assembly speaker Sheldon Silver -- an Orthodox Jew -- as 'Hitler.' But Paladino, plainspoken and seemingly earnest, was backed by the influential Tea Party movement, as well as by voters impressed with his message."

“New York Democratic Rep. Charles Rangel, facing ethics charges that have made him a pariah to many in his own party, handily won a primary Tuesday night -– a victory that nearly guarantees him another two years in Congress,” the Wall Street Journal writes.

“Christopher Cox, the wealthy son of the state Republican chairman and a grandson of President Richard M. Nixon, was crushed Tuesday night in his bid for the Republican nomination to represent Suffolk County in Congress,” the New York Times writes.

RHODE ISLAND: Providence Mayor David Cicilline (D) won a bloody four-way primary to succeed Patrick Kennedy in Congress. Cicilline is openly gay and would only be the fourth openly gay member of Congress if he wins.
