Democratic Sens. Bob Casey (Pa.) and Debbie Stabenow (Mich.) will return to the Senate, according to Associated Press projections.
Stabenow seemed vulnerable early in the cycle. But her opponent, former Rep. Pete Hoekstra (R), was never able to recover from a controversial television ad. President Barack Obama also proved to have strong coattails in Michigan, and the race was soon moved out of competitive categories.
Casey, however, got his scare at the end of the cycle. His self-funded opponent, Republican Tom Smith, was able to narrow the margin but couldn't get across the finish line.
