Senator Jon Tester of Montana was reelected in 2012. If he decides to run again when his current term expires, in what year will the election occur?

The correct answer is 2018. Senators have six-year terms and an unlimited number of possible terms, as long as the people support them. The senate and the house have unlimited number of terms possible unlike the president who can only be the president twice according to the constitution. Senator Tester will therefore be up for electio nagain in 2018 if the people choose to vote for him.
