During our lunch hour, the Roll Call politics team scoured fundraising reports filed with the Federal Election Commission and press releases that landed in our inboxes. Here’s our roundup of the winners and losers, as well as some noteworthy reports on this year-end filing day:

Winners:

• IA-03: Rep. Tom Latham (R) has quadruple the bank account of his opponent, Rep. Leonard Boswell (D), in his flagship Member-vs.-Member race. (via @shiratoeplitz)

• IN-05: On the morning of Rep. Dan Burton’s (R-Ind.) retirement announcement, former U.S. attorney Susan Brooks reported raising $107,500 and had $325,000 in the bank. Her chief competition for the GOP nod, former Rep. David McIntosh, has not filed his report yet. But Brooks brought in much more than the other Republicans who lined up to challenge Burton. She also has a head start on state Sen. Mike Delph, a former Burton aide, if he jumps into the race before the Feb. 10 filing deadline. (via @shiratoeplitz)
• AZ-Sen: Former U.S. Surgeon General Richard Carmona (D) brought in a solid $570,000 in the fourth quarter for his Senate bid. He raised far more than former Arizona Democratic Party Chairman Don Bivens, who brought in just $390,000 — $160,000 of which was from his own pocket. Bivens’ fundraising was a letdown after the third quarter, when he impressed Democrats by raising $345,000. (via @rollcallabby)

• UT-Sen: Sen. Orrin Hatch’s (R) big fundraising ways continued last quarter, when he brought in $1.5 million and ended December with $4.4 million on hand. He has GOP challengers taking him on in the April state party convention. (via @kyletrygstad)

Losers:

• IL-08: Rep. Joe Walsh (R) spent more money than he raised in the fourth quarter, bringing in $141,000 and spending $144,000. He’ll need to cut down on his burn rate to win re-election in this redrawn seat northwest of Chicago that favors Democrats. (via @shiratoeplitz)

• MT-AL: State Rep. Franke Wilmer, one of the top Democrats seeking this open seat, raised just $55,000 and had $54,000 on hand. State Sen. Kim Gillan, another top Democrat in the race, has yet to file. Meanwhile, businessman Steve Daines (R) announced raising $174,00 and had $631,000 cash on hand for the race to replace Rep. Denny Rehberg (R), who is running for Senate. (via @kyletrygstad)

• NM-01: Former state Rep. Janice Arnold-Jones (R) had a rough quarter — so bad her campaign did not include the number in the press release announcing that they filed the report. Arnold-Jones reported raising $31,000 and had $20,000 in cash on hand. Among the other Republicans running for this competitive open seat, Albuquerque City Councilor Dan Lewis has not yet filed and retired Army Sgt. Gary Smith’s report only listed a $50,000 personal contribution and $75,000 personal loan. (via @kyletrygstad)

Noteworthy:

• CA-??: Rep. David Dreier (R), whose district was obliterated by redistricting, raised a measly $10,200 in the fourth quarter. Even though he still has $729,600 in the bank, his recent fundraising will only stoke already persistent retirement rumors. (via @shiratoeplitz)

• NJ-09: Rep. Bill Pascrell raised twice as much as fellow Democratic Rep. Steven Rothman in the fourth quarter. Pascrell brought in $195,000, while Rothman raised $99,000. Rothman has the edge when it comes to cash on hand, however, with $1.7 million to Pascrell’s $1.5 million. It should be noted that neither Democrat knew they’d face each other until the end of the fourth quarter, when New Jersey’s redistricting commission published the state’s new map. (via @rollcallabby)

• OK-02: Retiring Rep. Dan Boren (D) appears set to leave Congress with a hefty amount of campaign cash in the event he wants to one day continue his political career. Boren had $748,600 in the bank at of the end of 2011. (via @shiratoeplitz)

• MO-??: Rep. Russ Carnahan (R) hasn’t told us which district he’s running in, but he’s still raising money. Carnahan reported raising $105,600 in the fourth quarter, giving him $449,000 in cash on hand. While not an awesome number for the incumbent and Show-Me State scion, it’s respectable for a candidate who has yet to disclose what his re-election plans are. (via @shiratoeplitz)
