While there are very few surprises expected in Tuesday’s congressional primaries, redistricting has provided some open seats and interesting match-ups. Here is what we’ll be watching for tonight:

The Rose Bowl: The GOP primary battle for Florida’s newly drawn 7th congressional district, which pits 10-term incumbent Rep. John Mica against freshman Rep. Sandy Adams, is the Rose Bowl of primary night. High-profile endorsements, accusations of ethics violations and a series of nasty ads have elevated the race into one of the most watched primary battles in the country.

As the New York Times reported, the race has become so heated that the two candidates longer speak, in large part, Adams said, because when she went to shake Mica’s hand at a recent event, he told her, “You will regret this for the rest of your life. I’ll destroy you.”

Mica is expected to pull off a win in the member-on-member battle, but he isn’t taking anything for granted and neither are we.

The Six Pack: Six Republicans are vying to fill Connie Mack’s Southwest Florida seat. According to a Public Policy Polling survey released last week, the race is a statistical tie between Trey Radel and Paige Kreegel.  Radel polled 25 percent and Kreegel 23 percent, well within the margin of error, which is plus-or-minus 4.38 percent. Gary Aubuchon was third with 16 percent, while Chauncey Goss had 14 percent, Byron Donalds had 13 percent and Joe Davidow was far behind with 2 percent.

Mack’s Momentum: With Mack expected to trounce his GOP rivals, Col. Mike McCalister and former Representative Dave Weldon, the only unknown in the GOP Senate primary will be Mack’s margin of victory. As Tampa Bay Times put it, “If Mack breaks 60 percent, he’ll have some momentum. If he doesn’t break 50, watch for Democrats to pounce.”

What Endorsements Will Earn You: Seven Republicans –Ron DeSantis, Richard Clark, Craig Miller, Billy Kogut, Alec Pueschel, Beverly Slough and Fred Costello– are running in the GOP primary for the 6th congressional district.

DeSantis, who has nabbed the endorsements of CFO Jeff Atwater and state Agriculture Commissioner Adam Putnam, leads the pack in fundraising with more than $404,000 as of June 30. Miller, meanwhile, has received endorsements from former presidential candidate Herman Cain, and former Florida Attorney General Bill McCollum.

A Gift For Grayson: Four Republicans are competing to see who will face former Rep. Alan Grayson, who recently asserted himself into the primary by launching an ad blitz against Osceola County commission chair John Quinones. By weakening Quinones, Grayson could help ensure that one of the other three GOP opponents could get the nomination tonight, setting up an easier election for Grayson in November.
