Mitt Romney is halfway to clinching to the Republican nomination for president.
Romney inched up to 572 delegates on Monday — exactly half the 1,144 needed — after the Tennessee Republican Party finalized delegate totals from its March 6 primary. Results in several congressional districts were too close to call on election night, leaving three delegates unallocated.
Romney got all three delegates. He also picked up a New Hampshire delegate who had been awarded to former Utah Gov. Jon Huntsman.
The Associated Press tally shows Romney winning 54 percent of the primary and caucus delegates so far, putting him on pace to clinch the nomination in June. His closest rival, Rick Santorum, has 273 delegates, followed by Newt Gingrich with 135 and Ron Paul with 50.
