Karl Rover, Former Senior Advisor and Deputy Chief of Staff to President George W. Bush, Wall Street Journal Columnist and Fox News Contributor, joined Fox News Radio's Guy Benson and Marie Harf the night before the midterm elections to give his insight. 

On his predictions for Tuesday: First of all, I think it all points to all a relatively close election in all three of the big baskets we're looking at.  There are four or five baskets, but the biggest baskets are in the Senate and in the House and in the governors and then we've got local offices and then referendums. I think my sense is we're such a polarized country and the map in the Senate, in particular,  is so polarized that we're likely to have a large number of openly contested races. Second thing is I think it's going to be the highest midterm turnout that we've had since 1966. Everybody's energized, both parties are.  (2:14)

On early voting numbers: Here's why you shouldn't put total confidence in the election numbers because we don't know how many defections there are and there are places where there are going to be defections from the party of the chose of the primary voter. Second of all, because we have a large number of people, like in Florida, who decline to state their party or in Texas whom have never voted in a primary.  (3:30)

On polls: I look at polls all the time. I'm involved in a super-pack and we drown in polls, but there was a golden age of polling. Everybody had a landline and we actually answered them and we're no longer there. Until we get better at whatever this new world is where we're all on our mobiles and even then we don't answer unrecognized phone numbers and we haven't yet figured out how to get this all done appropriately on the Internet. You have to look at averages and you have to realize it's an art not a science. (6:22)

On governors races: It's interesting a couple of states you mentioned there, South Dakota and Iowa, the Democrats have nominated moderate to moderately conservative candidates. The candidate of the Democrats in Iowa is a successful businessman running as a business oriented Democrat and the candidate in South Dakota is running as a somewhat pro-gun, pro-life, business oriented, farm oriented Democrat.  When they run that kind of candidate it helps in a state like Dakota. (7:01)

On a lot of people saying we don't know what's going to happen because of 2016: That's normal. In 2000, we had a number of people prematurely call Florida and as a result in 2004 despite the fact that Bush had 120,000 vote margin against John Kerry the networks would not call Ohio until almost 3 o'clock.  That was a reaction to having prematurely called Florida and everybody being juiced up by bad exit polls. (11:52)
