With the talk about stepping up and running for office, I feel that it's for the best that the deadlines are publicized.
The FEC actually has a .pdf file of this information and it's here.
You can click on it, but i'll post the information from that page here. And I know that some of the info on who is being opposed and who isn't might be inaccurate, and some of it was posted on a front page diary. Correct me if you have to do so. Or reassure me about some district.
And I know that the info on deadlines on Politics1 may contradict the FEC information, but i'll take the FEC's word over Politics1's word. But, if in doubt, check with your state.
Deadlines (from earliest to latest):
(under the fold)
Illinois - December 19th, 2005 (Biggert [13], Manzullo [16] and LaHood [18] are officially unopposed right now. Other candidates quality may vary.)

West Virginia - January 28th, 2006 (We have a candidate facing Shelly Moore Capito, so yay for that)
Kentucky - 4PM on January 31st, 2006 (Davis [4] and Rogers [5] are unopposed. I hear that Northup [3] and Lewis [2] are going to get opponents, or at least Lewis)
Ohio - February 16th, 2006 (Chabot [1], Oxley's seat [4], Boehner [8], and Tiberi [12] are unopposed)
Indiana - Noon on February 17th, 2006 (Burton [5] is unopposed)

Maine - March 15th, 2006 (No worries, we have both House seats and Michael Brennan is running against Olympia Snowe)
Idaho - March 17th, 2006 (We have candidates, and they probably don't have a great chance, but oh well)
Iowa - March 17th, 2006 (Latham [4] is unopposed at the moment)
Utah - March 17th, 2006 (Bishop [1] and Cannon [3] are unopposed. Imagine that, a lack of Democrats in Utah. That could change, I remember Utah having a full slate in 2004.)
Montana - March 23rd, 2006 (Rehberg has an opponent already)
Missouri - March 28th, 2006 (Blunt [7], Emerson [8], and Hulshof [9] don't have opponents. Sam Graves [6] might have an opponent in Sara Jo Shettles, but I'd be more comfortable if he had an opponent with a website)
New Mexico - March 29th, 2006 (Steve Pearce [2] doesn't have an opponent, but hopefully somebody will file)

New Jersey - April 10th, 2006 (Smith [4] and Frelinghuysen [11] are unopposed by the Democratic Party. Saxton apparently has one opponent. But, he could use more.)
Virginia - 5pm on April 14th, 2006 (Forbes [4], Goode [5], Goodlatte [6], Cantor [7], and Wolf [10] are unopposed by the Dems. Although candidates might be nominated by convention too, or something in a convention could lead to a primary, but that's probably wishful thinking)
North Dakota - April 17th, 2006 (The only people who'll sweat over this deadline are people who want to find a candidate to face Conrad or Pomeroy)
Georgia - April 28th, 2006 (Westmoreland [8 aka 3], Linder [6], Price [7], Norwood [9], Deal [10], and Gingrey [11] are unopposed by the Dems right now. But potential candidates might still be consulting the new maps)

New York - July 13th, 2006 (Peter King [3], and Sherry Boehlert [24] don't have Democratic opponents yet. Fossella [13] might get a big challenge too.)

Louisiana - August 11th, 2006 (McCrery [4], Alexander [5], Baker [6], and Boustany [7] don't have any challengers, but I would hope that somebody in Louisiana would file in the next 9 months)
And a state i'm not sure about:
Connecticut - The FEC lists the filing deadline as 14 days after the convention. But then again, we have candidates in Connecticut too.

So, feel free to use this as another place for rumors or corrections. And Fielding 435 would be pretty cool too.
