— -- Most of the time it seems like the 2016 presidential race is all about the candidates. But the voters are just as important as the contenders, so ABC News has decided to turn the lens around to see what the trail looked like on the final full day of campaigning before Monday's Iowa caucuses -- through the voters' eyes.

No matter whether a candidate is a Republican or Democratic, a common theme this cycle is the selfie.

Here's one a voter took with former Secretary of State Hillary Clinton after having a conversation about protecting marriage equality, according to the picture's caption.

On the Republican side, both billionaire real estate mogul Donald Trump and former Pennsylvania Sen. Rick Santorum -- the winner of the 2012 Iowa caucuses -- also kept their selfie game strong.
