Don't miss Fox News Channel's election coverage tonight, as Bret Baier and Megyn Kelly co-anchor live, continuous updates on key races, plus must-see political analysis, starting at 6p ET.

With so many races to follow and so many results to track, Baier dropped by "The Real Story" this afternoon to share some helpful tips for how you can watch all the election coverage like a pro.

He also revealed that Fox News could be calling which party wins control of the Senate as early as 10 or 11p ET.

So, here's what you should keep an eye on hour-by-hour tonight, as polls around the country close.

Krauthammer on Midterm Election: 'This is Liberalism on Trial'

7:00p ET polls closing - Georgia, Indiana, Kentucky, Vermont, Virginia

We should be able to see early in the night if Democrat challenger Alison Lundergan Grimes is making a stand in Kentucky. If Kentucky can't be called for Republicans around 7p ET, then that means Sen. McConnell is getting a bigger fight than expected.

In Georgia, the question is if either candidate can get to 50 percent. If not, it will be called as a December runoff.

7:30p ET polls closing - North Carolina, Ohio, West Virginia

North Carolina is a must-win for Democrats. If GOP candidate Thom Tillis even makes it close with incumbent Sen. Kay Hagan, it bodes very well for Republicans.

8:00p ET polls closing - Alabama, Connecticut, Delaware, DC, Florida, Maine, Maryland, Massachusetts

New Hampshire is another key state, and Shaheen holding off Republican challenger Scott Brown is all but a necessity for Democrats to block GOP Senate control.

9:00p ET polls closing - Arizona, Colorado, Kansas, Louisiana, Michigan, Minnesota, Nebraska, New Mexico, New York, North Dakota, South Dakota, Texas, Wisconsin, Wyoming

The Kansas race between Republican Sen. Pat Roberts and independent Greg Orman is absolutely huge and could be the whole ballgame. Right now, it's so close that no one even has a good sense of where the race is at.

Louisiana, on the other hand, looks like it's headed for a December 6 runoff, since neither Democratic incumbent Mary Landrieu, nor Republican challenger Rep. Bill Cassidy is likely to get 50 percent of the vote.

10:00p ET polls closing - Iowa, Montana, Nevada, Utah

Iowa is another must-win for Democrats. If Republican Joni Ernst beats Democrat Bruce Braley in their neck-and-neck race, it's difficult to see how Democrats hold the Senate.

In fact, if Republicans get a few things to break their way early in the night, by 10 or 11p ET, Fox News Channel could call control of the Senate.
