The New York Times'  Jeff Zeleny and Jim Rutenberg: " Nomination His, Romney Steps Up Attack on Obama"  Mitt Romney, having initially weathered the first sustained general election attack, is entering a critical 90-day stretch to the Republican convention on relatively equal footing with the White House and is unleashing a new offensive to win over independent voters and further undermine confidence in President Obama's stewardship of the economy.

Politico's Ginger Gibson: " Romney clinches GOP presidential nod " Mitt Romney's long and arduous path to the Republican presidential nomination is officially over.

The Washington Posts' Nia-Malika Henderson: " Romney clinches nomination, attacks Obama on Solyndra" Mitt Romney and his allies opened a multi-pronged attack Tuesday  on President Obama's stewardship of taxpayer dollars, as Romney won the Texas primary and clinched the Republican presidential nomination.

Bloomberg's Don Frederick: " Romney Seals Republican Nomination With Victory in Texas" Mitt Romney clinched the Republican presidential nomination by winning the Texas primary, taking the contest by a wide margin that put him over the top in the delegate chase. Romney now has 1,183 delegates, capturing at least 97 of the 152 awarded in Texas based on the candidate's statewide vote total yesterday, the Associated Press reported.

USA Today's Jackie Kucinich: " Romney clinches 1,144 delegates, but buzz is about Trump" Mitt Romney finally clinched the Republican presidential nomination Tuesday, but all the chatter around his campaign was about Donald Trump.  Romney has been without a major competitor in the Republican race since former Pennsylvania senator Rick Santorum dropped out in April, but the Texas primary provided the 58 delegates he needed to reach the magic number: the 1,144 delegates required to secure the nomination.  LINK

Wall Street Journal's Patrick O'Connor and Laura Meckler: " Romney Says Win Secures GOP Nod" Mitt Romney Tuesday night claimed his win in the Texas primary gives him the requisite number of delegates to clinch the Republican presidential nomination.  "I am honored that Americans across the country have given their support to my candidacy and I am humbled to have won enough delegates" to be the GOP nominee, Mr. Romney said in a statement.  LINK
