I believe Utah has a primary election coming up soon, so Republicans can select the other candidate for the general election.
The winner of the Republican primary is virtually certain to win the general election in November, so this primary is the last best chance to get rid of Romney.
The Utah primary convention was held a month ago with none of the several Republican candidates getting 60% of the vote. There is a run off election scheduled for June 26 between Mitt Romney and Mike Kennedy to determine the Republican candidate for November’s election.
“According to KSL, Kennedy, who in addition to being a state legislator is also a doctor and lawyer, defeated Romney in the Utah Republican Convention which took place earlier this year. Romney drew 49 percent of the votes while Kennedy took 51 percent. In order to advance in the election and win the nomination, a candidate must earn 60 percent of the votes. The win and respective loss for Romney meant he was unable to avoid the upcoming June primary election.”
Twenty-four years ago, Mitt Romney began his political career by mounting a surprisingly strong challenge to then-Sen. Ted Kennedy (D-Mass.). Romney came up short, but his first race put him on a path that led to the Republican presidential nomination in 2012.
Now, running to replace retiring Sen. Orrin Hatch (R-Utah), Romney is likely to exact a small measure of revenge against a Kennedy — though not one who’s related to the Massachusetts clan. A poll conducted last week showed Romney leading state Rep. Mike Kennedy (R) 65 percent to 23 percent.
Romney is all but certain to skate to the Senate in November. He will face Salt Lake County Councilwoman Jenny Wilson (D). Utah has not elected a Democrat to the Senate since Frank Moss won reelection in 1970. Hatch beat Moss six years later."
