Tom Bevan, Executive Editor Of Realclearpolitics.com, joined Fox News Radio's Marie Harf to discuss polling the midterm election. 

On how the pollsters did in 2018: Pretty good. I thought the pollsters did a decent job. There were some states that we didn't have a lot of data in, but generic national vote pretty spot on. Our RealClearPolitics average was right about where it ended up. Ironically enough, the one state where we had the most polling, which was Florida, was a surprise. (5:25)

On Florida: I think it is a hard state to poll. I think harder than many because there are so many different components to it, but at the end of the day it comes down to what do pollsters think the electorate is going to look like on Election Day, who is going to turn out and vote.  (7:50)

On when they start 2020 polling: We haven't started aggregating any polling on 2020. There have been a couple polls on 2020 and at this point they don't mean anything.  It's all name id. It's Joe Biden and Elizabeth Warren. But, clearly the race has started and you've seen now more and more folks saying they're going to get in. I'm excited about it. I think it's going to be just an absolute circus. (9:15)
