The presidential race has dominated the American news cycle for month, but at Firehouse 51, there's a different election capturing everyone's attention.

When Chicago Fire returns on Tuesday, there are just six days left to go until Casey (Jesse Spencer) officially goes up against Becks (Armand Schultz) for Alderman. And his girlfriend Dawson (Monica Raymund) isn't letting anyone in the house forget it.

"If Casey is going to beat Becks in the poll, we need all hands on deck," she tells the group in The Hollywood Reporter's exclusive video from Tuesday's episode as she hands out flyers.

Although Casey is down five points in the latest polling, it sounds like Casey's flirtation with politics is just beginning.

"If you put yourself in that position, you get caught in the middle really, really quickly, so we're going to see him struggle with political corruption pretty quickly," Spencer tells THR. "I talked to an Alderman who is a fireman and a police man, and he said what you hear is literally the tip of the iceberg. Its full on."

Spencer acknowledges that Casey entered the political realm "naively," but says he will have to get caught up to speed quickly.  

"Money talks and you've got to be able to roll with the punches and so it's kind of an interesting position for a guy who's morally upstanding," he says. "Because he's an independent, he doesn’t owe anybody anything really so there's going to be a lot of friction. People are going to be throwing a lot of things at him."

And while Dawson may be fully supportive of her beau's ambitions now, that might not stay the same. "I don’t think its going to be good," Spencer says when asked about how Casey's new challenges will impact his relationship with Dawson. "There's going to be a political consultant who comes in and turns his head a bit."

Meaning: It's time to cherish Casey and Dawson in a good place before things go south.
