Think of it as a rematch of a rematch.
In New Hampshire, Democratic Congresswoman Carol Shea-Porter is battling Republican Frank Guinta for the third time in a row. Each has beaten the other before – Guinta defeated Shea-Porter during the 2010 Tea Party wave, and Shea-Porter won her seat back in 2012.
You wonder if it starts to get boring when you're hitting the same rival over and over again.
"Well, I know what he's going to say, that's for sure," says Shea-Porter.
Guinta admits the same: "I mean, it is kind of old hat."
