PRESIDENT OBAMA

The New York Times' Peter Baker: " Obama Finds Campaigning Rules Clock" By the time President Obama took the stage at the Fox Theater here, he was in the 18th hour of a 19-hour day. His tie was still knotted to the top as he launched into his stump speech, attacking his opponent's record and defending his own. "I still believe in you," he said, "and I hope you still believe in me." LINK

USA Today's David Jackson: " Aide: Obama to keep up attacks on Romney business record" Don't expect President Obama to stop attacking Mitt Romney's business record any time soon. Former spokesman Robert Gibbs said the issue is relevant because Bain Capital, Romney's former private equity firm, is about making money, even if it means cutting jobs and shutting down companies.

MITT ROMNEY

The Washington Times' Seth McLaughlin: " Home field disadvantage: Romney's winning map excludes Massachusetts" If Mitt Romney wins the White House this fall, he will in all likelihood do so while beating some very long historical odds. Polls suggest the presumptive Republican nominee has little chance of carrying Massachusetts, the state he served as governor from 2003 to 2007, against President Obama in November. LINK

The Boston Globes' Stephanie Ebbert: " Mass. GOP moves to invalidate caucus ballots" A month after former Governor Mitt Romney's loyalists were trounced by supporters of Ron Paul in his home state caucuses, the Massachusetts Republican Party is trying to invalidate results - a move that has infuriated rank-and-file Republicans who accuse establishment insiders of bending the rules to their own benefit.

WISCONSIN

Politico's Robin Bravender: ' Stakes high in Wisconsin's other recalls" With both sides pouring millions of dollars into the Scott Walker recall campaign and the national focus firmly affixed on the Wisconsin GOP governor's fate, it's easy to overlook the consolation prize on June 5: the state Senate. Although they're getting just a fraction of the attention and cash going into the top of the ticket race, the four Wisconsin state Senate recall elections on the ballot are nothing to sneeze at.

CALIFORNIA

The Los Angeles Times' Robin Abcarian: " California is a Romney home state too" David and Cristina Sear were walking their Doberman pinschers in this seaside neighborhood when a big U-Haul truck pulled up around the corner from the $12-million beachfront home Mitt and Ann Romney had just bought. The driver could not negotiate the steep turn onto Dunemere Drive, a narrow cul-de-sac with no sidewalks. LINK

The New York Daily News' Meghan Neal: " Newport Beach sends Obama $35K bill for campaign visit" A wealthy Southern California beach town has slapped President Obama with a $35,000 bill to cover costs from a February campaign visit.   LINK

Officials say Obama's visit cost the city - blessed with a stunning shoreline and multi-million-dollar mansions - thousands of dollars to pay for extra police protection.  LINK
