MITT ROMNEY: ABC News' Chris Good: " Michigan GOP Changes Delegate Rules, Gives Primary Edge to Romney" The Michigan Republican Party voted to break a delegate tie Wednesday night, awarding 16 delegates to Mitt Romney and 14 to Rick Santorum. The decision, which broke a 15-15 tie that would have resulted under the pre-primary interpretation of the rules, caused disbelief at Rick Santorum's campaign. A spokesman rejected the decision.

The New York Daily News' Jonathan Lemire: " After Michigan and Arizona wins in GOP race, front-runner Mitt Romney sets sight on Super Tuesday" All eyes are now on Ohio in the Republican race for the White House. A day after Mitt Romney's pair of victories - a squeaker in Michigan and a rout in Arizona - allowed him to regain some momentum in the topsy-turvy GOP primary campaign, the candidates sprinted into Super Tuesday battlegrounds. LINK

The New York Times' Michael Barbaro and Jeremy Peters: " Romney Reopens Whatever-It Takes Playbook" When Gov. Rick Perry began rising in the polls, Mitt Romney was ready with a potent debate-night assault: under Mr. Perry, illegal immigrants in Texas received a $100,000 tuition break. LINK

The Los Angeles Times' Matea Gold and Melanie Mason: " Romney campaign turns to shallow pockets" fter locking up much of the Republican establishment's heavyweight fundraisers, Mitt Romney is going after the little guy. "Donate $3 today to be automatically entered to be Mitt's special guest for Election Night on Super Tuesday," reads an email appeal from the Romney campaign to supporters. LINK

Boston Globe: " Similar Romney ads raise questions" The two television ads are almost indistinguishable. In both, former Bain Capital executive Robert C. Gay tells the tale of Mitt Romney's role in leading a search for Gay's missing daughter, interspersed with footage of New York and flashes of Romney. LINK

Bloomberg's Julie Hirschfield: " Romney Presses for Super Tuesday Primary Wins to Allay republican Doubts" Mitt Romney is pressing to refocus the Republican presidential race on jobs and the economy in the sprint to potentially pivotal Super Tuesday contests next week, looking to blunt rival Rick Santorum's bid to sow doubts about his record on social issues. LINK

RICK SANTORUM: ABC News' Shushannah Walshe: " Santorum: We Have a 'Guerrilla Campaign'" Rick Santorum defined his campaign, which he says has none of the frills or trappings of Mitt Romney's, as a "guerrilla campaign" Thursday. He raised $9  million in February alone, but the candidate believes as the race approaches Super Tuesday, he will be outspent by his rival. "Look, I don't have billionaires giving me tens of billions of dollars to super PACS," Santorum said. LINK

The Washington Post's Nia-Malika Henderson and Philip Rucker: " Rick Santorum stumps in Newt Gingrich's territory: Georgia" Battling for Super Tuesday dominance in the South, Rick Santorum ventured into Newt Gingrich's back yard on Thursday to pitch himself as the only conservative option left in what he says is a two-man Republican presidential race that does not include Gingrich. LINK

Politico's James Hohmann: " In Washington state, Rick Santorum relies on religious voters" Rick Santorum thinks a win in Washington's caucuses this weekend will help him regain the momentum he lost in Michigan. He made plain during a Thursday rally at a church here that he's counting on social conservatives to make that happen. LINK

The Hill's Daniel Strauss: " Santorum accuses Romney of rigging Michigan's delegate distribution" Rick Santorum is accusing Mitt Romney of rigging the delegate count in Michigan and calling on further scrutiny of how the delegates were distributed. The Michigan Republican Party is awarding Romney two-at large delegates, leaving him with 16 delegates to Santorum's 14, according to the Detroit Free Press. LINK

NEWT GINGRICH: The Wall Street Journal's Elizabeth Williamson: " Strong Views of Gingrich in District He Represented" Patricia Carter taught Newt Gingrich's daughter in first grade and worked for years to get him elected to Congress. Now, as Mr. Gingrich banks on the South to revive his presidential hopes, she doesn't plan to vote for him, still stung by memories of his walking out on his first wife three decades ago. LINK

GOP RACE: The Washington Times' Rachel LaCorte: " Washington caucuses are last stop before Super Tuesday" The fight to emerge as the Republican challenger to President Obama turns on Saturday to Washington state - a Democratic bastion known not just for majestic mountain ranges and good coffee, but also for independent-minded voters. LINK

USA Today's Gregory Korte: " GOP delegates still at stake" By exploiting state rules that often award delegates to winners of individual congressional districts, former Pennsylvania senator Rick Santorum picked up 14 delegates in Michigan on Tuesday, despite losing the statewide vote. President Obama used a similar strategy in 2008, playing a sort of presidential nomination "moneyball" to target individual congressional districts where a modest investment could pick up delegates even while losing the statewide popular vote.
