When it comes time for November's general elections the swing states will either make or break the candidates presidency—and the markets know it.

Four key swing states—Florida, Ohio, Pennsylvania and Virginia—have seen economic boosts since the year began. Though the nation's economy has been improving overall—the GDP rose by 1.1% in Q1—these four states have enjoyed growth on par or above the national average during the last three months of 2015 and the first three months of this year, the Wall Street Journal reports.

Florida will be one of the most influential swing states in this year's election, and it ranked 10th in economic growth out of all 50 states, with a 1.4% boost in Q1 following its 2.9% growth in Q4. Ohio followed behind, ranking 25th in all 50 states in economic growth, posting a 1.4% increase in Q1. Then there were Pennsylvania and Virginia. Several of the states have also reported lower unemployment rates than the national average. [WSJ]
