Romney picks up an easy win in D.C. WASHINGTON, April 3 (UPI) -- Mitt Romney picked up another 16 delegates in the District of Columbia Tuesday where results showed he won the Republican presidential primary handily. CNN said just after the polls had closed that it had put a "W" in the former Massachusetts governor's column. With 58 percent of the District's precincts counted, Romney had 70 percent of the vote to 12 percent for U.S. Rep. Ron Paul of Texas and 11 percent for former U.S. House Speaker Newt Gingrich of Georgia. Former U.S. Sen. Rick Santorum of Pennsylvania was not on the ballot. Romney also won in Maryland and Wisconsin Tuesday. CNN said by its count Romney has more than half of the 1,144 delegates he needs to win the GOP nomination.
