John McCain and Al Sharpton. When John McCain ran for president in 2008, some commentary focused on the age gulf between him and Barack Obama. So McCain's announcement Tuesday that he will seek a sixth term in the Senate in November suggests that he must be near the upper end of the age range of Senate. Which he is. But, if McCain, who is now 78, is reelected, he probably won't even be one of the three oldest senators in the 115th Congress, much less history.
This isn't really the case in 2016. Mitt Romney won 17 of the 24 states where Republicans are facing re-election. Of the 7 states Obama won most were low-single-digit victories, and the only blowout was his home state of Illinois.rizona-John McCain won re-election easily in 2010, but he will be 80 years old in 2016 and may or may not run for re-election. He is probably safe if he runs again, but if he doesn't the race could get interesting. In 2012, Republican Jeff Flake won the junior seat from Arizona by just 3 points.
