MITT ROMNEY: ABC News' Emily Friedman and Michael Falcone: " Mitt Romney Sweeps, Pegs President Obama as Out of Touch" After sweeping wins in Wisconsin, Maryland and Washington, D.C.'s primaries, Mitt Romney took to the stage today to deliver a pounding critique of President Obama, fully ignoring his GOP rivals and instead painting the president as "out of touch."

Politico's Reid J. Epstein: " Mitt Romney to Rick Santorum: Game over" Mitt Romney wants you to believe the contest against his persistent Republican presidential challengers is over.

Bloomberg's John McCormick and Lisa Lerer: " Romney Sweeps Three Primaries to Keep Lead Over Santorum" Mitt Romney swept to victory in a trio of primaries, wins that accelerate his path to the Republican presidential nomination and intensify questions about the candidacy of chief rival Rick Santorum.

LINK

USA Today's William M. Welch and Judy Keen: " Romney sweeps D.C., Maryland and Wisconsin" Former Massachusetts governor Mitt Romney swept three Republican presidential primaries Tuesday, winning contests in Wisconsin, Maryland and the District of Columbia and tightening his grip on the nomination.

The New York Times' Jim Rutenberg and Jeff Zeleny: " Romney Adds 3 Victories and Clashes With Obama" Mitt Romney tightened his grip on the Republican nomination on Tuesday with a sweep of the primaries in Wisconsin, Maryland and the District of Columbia, and found himself in his first direct engagement with President Obama, an unmistakable signal that the general election would not wait for internal Republican politics.

The Washington Post's Dan Balz and Philip Rucker: " Mitt Romney wins Wisconsin, Maryland, D.C. primaries" Mitt Romney captured presidential primaries in Maryland, the District and battleground Wisconsin, the biggest prize of the day, to complete a momentum-building, three-contest sweep Tuesday that cemented his status as the almost certain Republican nominee and put new pressure on rival Rick Santorum to reassess his candidacy.

The Hill's Josh Lederman: " Romney wins Wisconsin primary, increases lead in delegates" Mitt Romney won Wisconsin's primary Tuesday night, increasing the pressure on his rivals to exit the GOP presidential race.

RICK SANTORUM: Boston Globe's Glen Johnson: " Santorum Begins to concede 2012 race with warning" Faced with increasingly long odds of catching Mitt Romney for the Republican presidential nomination, and the near certainty of his rival securing it before any possible brokered convention in Florida this summer, Rick Santorum has begun to concede the 2012 race in his own way. LINK

The Wall Street Journal's Colleen McCain Nelson and Danny Yadron: " Santorum Prepares for Last Stand" With its hope of denying Mitt Romney the Republican nomination dimming, Rick Santorum's campaign has settled on an all-in strategy focused on Pennsylvania, a state that could provide a win-or-go-home moment for the struggling candidate later this month. The former Pennsylvania senator has long pointed to his home state as a pivotal proving ground in this primary season. LINK

GOP FUNDRAISING / OTHER: The Washington Times' Sean Lengell: " GOP making gains on fundraising front" The 2010 midterm elections were a dream come true for the Republican Party at the ballot box but a nightmare for its bank accounts.
