Several caucuses and primaries took place during February, and Santorum won three in a single night early in the month, propelling him into the lead in national and some state polls and positioning him as Romney's chief rival. Days later, Romney told the Conservative Political Action Conference that he had been a "severely conservative governor" (while during his term in 2005 he had maintained that his positions were moderate and characterized reports that he was shifting to the right to attract conservative votes a media distortion). Romney won the other five February contests, including a closely fought one in his home state of Michigan at the end of the month. In the Super Tuesday primaries and caucuses of March 6, Romney won six of ten contests, including a narrow victory in Ohio over a vastly outspent Santorum. Although his victories were not enough to end the race, they were enough to establish a two-to-one delegate lead over Santorum. Romney maintained his delegate margin through subsequent contests, and Santorum suspended his campaign on April 10. Following a sweep of five more contests on April 24, the Republican National Committee put its resources to work for Romney as the party's presumptive nominee. Romney clinched a majority of the delegates with a win in the Texas primary on May 29.
