WASHINGTON, May 9 (UPI) -- Presumptive Republican U.S. presidential nominee Mitt Romney, with three more states in his win column Tuesday night, went after his Democratic opponent.
The former Massachusetts governor, whose list of GOP rivals has been winnowed to U.S. Rep. Ron Paul of Texas through months of primaries and caucuses, picked up bunches of delegates in Indiana, North Carolina and West Virginia, closing in on the 1,144 he needs to clinch the party's nomination at the national convention in Tampa, Fla., this summer.
