Tuesday was filled with primary contests across the country, but the big news came out of Mississippi, where six-term U.S. Sen. Thad Cochran escaped Chris McDaniel in the state's runoff election. Cochran narrowly defeated his Tea Party challenger and will now seek his seventh term in November.

In Oklahoma, Sen. Jim Inhofe cruised through his GOP primary for re-election and Congressman James Lankford secured the state's other nomination for Senate. This is the first time in modern history Oklahoma has both Senate seats up for grabs because Sen. Tom Coburn is leaving Congress two years early because his cancer has returned.

As expected, Maryland Lt. Gov Anthony Brown secured the nomination for governor over Attorney General Doug Gansler and Del. Heather Mizeur. Brown will face GOP winner Larry Hogan in November.
