Mitt Romney may be the supposed frontrunner for the Republican presidential nomination – but he’s not the most popular GOP candidate in Minnesota. Texas Congressman Ron Paul swept the 3rd, 5th and 6th Congressional District conventions over the weekend. Paul landed nine of nine state delegates to the Republican National Convention in Tampa, Florida. Paul also won one delegate in Minnesota’s 7th District March 31st while Rick Santorum picked up two. The four remaining districts will chose their delegates and alternates this weekend. Paul’s campaign is banking on Santorum backers throwing their support behind him. Romney finished third in Minnesota’s February caucuses which were non-binding. Rick Santorum won the straw poll vote during the Brown County Republican Caucus in March, with Ron Paul coming in a close second. The results were the same in many other local-area counties, although Paul won in Blue Earth County. But with Santorum out of the race now many of his delegates have been forming a “Conservative Unity” coalition with Ron Paul delegates. Southern Minnesota’s 1st Congressional District Convention is this weekend, and the State GOP Convention takes place May 18th.
