PRESIDENT OBAMA: The New York Times' Peter Baker and Dalia Sussman: " Obama's Switch on Same-Sex Marriage Stirs Skepticism" Most Americans suspect that President Obama was motivated by politics, not policy, when he declared his support for same-sex marriage, according to a new poll released on Monday, suggesting that the unplanned way it was announced shaped public attitudes. LINK

The Washington Times' Dave Boyer and Susan Crabtree: " Obama noncommittal on repeal of DOMA" Although he came out in support of same-sex marriage last week, President Obama on Monday declined to say whether he would work with congressional Democrats to repeal the Defense of Marriage Act. LINK

The Los Angeles Times' Paul West and Michael Memoli: " Obama campaign attack ad calls Romney a 'job destroyer'" President Obama on Monday intensified a potentially crucial phase of his reelection try: an effort to define Mitt Romney in negative terms before voters have time to form a more positive image of the Republican challenger. LINK

The Hill's Amie Parnes : " Obama attack ad steals Gingrich tactic and puts spotlight on Bain" President Obama sought to turn Mitt Romney's business background against him on Monday by launching an aggressive attack on his years in private equity. The effort included a new television ad focused on the shuttering of GST Steel, a Missouri steel mill purchased, then closed - with a loss of more than 750 jobs   by Bain Capital, the investment firm founded by Romney. LINK

Bloomberg's John McCormick and Hans Nichols " Obama Carolina Convention Plans Going Awry for Democrats" President Barack Obama's decision in February 2011 to hold the Democratic National Convention in North Carolina looked like a bold move to reclaim a state he'd won in 2008. Today, it's more like an awkward fit. LINK

The Wall Street Journal's Neil King Jr. and Mark Maremont: " Obama Ad Targets a Bain Investment." President Barack Obama's re-election team is using a five-state advertising buy to launch a long-expected effort to paint Mitt Romney as a callous corporate raider, highlighting investments he made as head of the private-equity firm Bain Capital. The push marks the Obama camp's first big attempt to define the presumptive Republican nominee negatively in voters' minds. It is aimed explicitly at working-class voters in Iowa, Ohio, Pennsylvania, Colorado and Virginia. LINK

RON PAUL: ABC News' Jason Volack: " Ron Paul: Winding Down, But Not Out" Ron Paul's long-shot presidential campaign started winding down today - done in by the candidate's lack of funds, senior aides admit. "It was a financial consideration definitely," campaign spokesman Gary Howard said. The 76-year old Texas congressman's coffers have dried up recently and actively campaigning in the 11 states yet to hold primaries would have thrown the campaign into debt - something Paul strongly opposes. LINK

The Washington Post's David Fahrenthold: " Paul stops spending money but doesn't stop campaigning" On Monday, Rep. Ron Paul made clear that the last act of his presidential bid would be as un­or­tho­dox as all the rest of it. Paul, the Texas congressman and perennial GOP long shot, said he would stop spending money in the 11 states with upcoming party primaries. LINK

Politico's James Hohmann: " Ron Paul's message to the GOP" Ron Paul sent a message to the GOP establishment Monday that he's not looking to cause mayhem at this summer's Republican National Convention. By announcing that he won't compete in the remaining primaries, Paul tacitly assured the party that he didn't intend to disrupt the likely Tampa coronation of Mitt Romney. And he also telegraphed to even the hardest core of his hope-trumping-evidence supporters that he might not, after all, be the 2012 nominee. LINK
