In the weekend contests, Mitt Romney won handily in Puerto Rico's presidential primary, while no official winner was declared in the Missouri Caucus. 

Romney took an overwhelming 83 percent of the vote in Puerto Rico, while Rick Santorum claimed 8 percent. Neither Newt Gingrich nor Ron Paul actively campaigned in the U.S. territory.

In Missouri, local caucuses elected delegates to advance to congressional district and state conventions, where the delegates will be bound to presidential candidates. No straw poll was conducted. However, Rick Santorum won Missouri's non-binding "beauty contest" primary on February 7, and it is a safe to assume that he will fare well at the state convention in April.
