Sen. Michael Bennet (D-Colo.) announced Tuesday he raised more than $1.4 million last quarter. His campaign said part of the haul came from 12,000 new donors. It declined to reveal its cash on hand.

Bennet's primary challenger, former state House Speaker Andrew Romanoff, has yet to release his first quarter numbers.

Former Lt. Gov. Jane Norton, the leading candidate in the Republican primary, announced last week that she raised $816,000 in the first quarter – a 48 percent increase over the previous term, her campaign said.

Florida U.S. Senate candidate Marco Rubio (R) on Tuesday announced he is rescheduling a pending campaign trip because his father has been diagnosed with another bout of lung cancer.

Rubio, who is running against Gov. Charlie Crist for the GOP nomination for the seat formerly held by retired Sen. Mel Martinez (R), issued this statement: "Unfortunately, my father, Mario Rubio, has been diagnosed with a recurrence of lung cancer. This will require me to return to South Florida. We are in the process of rescheduling some of the coming days’ events and look forward to continuing our conversation with voters in these communities in the near future."

Rubio's revised schedule includes three stops next Tuesday in The Villages, followed by stops in Belleview and St. Augustine on Wednesday. Subsequent stops are being rescheduled.

So how much money did former Sen. Dan Coats (R-Ind.) make as a lobbyist after he left the Senate? Coats isn’t saying, and his campaign appears to have missed the deadline to answer that question.

Coats’s Senate campaign has yet to file his personal financial disclosure (PFD) form.

According to the Federal Election Commission website, PFD’s “must be filed within 30 days after the individual becomes a candidate or by May 15 of the same calendar year, whichever is later, but in any event at least 30 days before the primary or general election.”

It’s past that 30-day window before the May 4 primary, and Coats has been in the race for longer than 30 days, too.

Democrats are eagerly awaiting the information. They have made plenty of hay about Coats’s work as a lobbyist. They point out that in a recent television interview, he declined to say how much money he made lobbying.

UPDATE 9:53 p.m.: Coats spokesman Pete Seat said the campaign will file for an extension.

"A letter formally requesting an extension will be filed tomorrow with the Senate committee, a common practice," he said. "The disclosure form is being prepared and will be filed soon."

UPDATE 10:24 a.m. Wednesday: Filing for an extension may be a common practice, but it turns out it's actually too late in this case.

According to Senate instructions: "An extension granted to a candidate is ineffective past the date such extension will result in a report being filed later than 30 days prior to an election in which the reporting individual is a candidate."

That means even if Coats's campaign asked for an extension, it wouldn't have gotten one past April 4, which would have been 30 days before the May 4 primary.

Michigan House Republican Leader Kevin Elsenheimer announced Tuesday he will not seek the GOP nod in the race to succeed Rep. Bart Stupak (D-Mich.).

"While it would have been an honor to serve in Congress, I want to spend more time closer to home and representing the largest congressional district east of the Mississippi would make that nearly impossible," Elsenheimer said in a statement. "After discussing it with my family, I concluded that my priorities are right here at home."

Stupak revealed last week he would not seek a 10th term in Congress.

Meanwhile, state Rep. Joel Sheltrown (D) announced Monday he would run for the seat.

Former Sen. Rick Santorum (R-Pa.) will travel to South Carolina next week, a state that holds a key presidential primary contest every four years.

The conservative's political action committee announced the trip Tuesday, saying that he will take a two-day swing through the state next Monday and Tuesday.

Santorum, who lost to Sen. Bob Casey (D-Pa.) in 2006, has been open about his desire to explore a 2012  presidential bid.

The ex-senator has not yet announced the cities he will visit or the events he will attend.

Rep. Paul Hodes's (D-N.H.) Senate campaign has seen its fundraising dip slightly from the last quarter of 2009, but it still pulled in a decent $665,000 in the first quarter of 2010.

Hodes's campaign said it entered this month with $1.7 million in the bank.

He has been raising money stride-for-stride with GOP favorite and former state Attorney General Kelly Ayotte, who has yet to announce her first-quarter totals.

Ayotte faces a primary, though, and a pair of self-funders have already banked $1 million for the race. Businessman Bill Binnie raised $400,000 in the first quarter and previously self-funded more than $1 million, while businessman Jim Bender loaned his campaign $400,000 last quarter, raised $100,000 and had $1 million cash on hand.

Sen. Blanche Lincoln (D-Ark.) wasn't outraised in the first quarter by as much as previously thought, but she did spend heavily.

Lincoln's campaign just came out with some more specific numbers. It turns out she raised more than $1.3 million (versus the "more than $1 million" previously reported) and has $4.3 million on hand. Lincoln's cash on hand dropped by about $700,000, meaning she spent heavily -- about $2 million -- defending herself in the primary.

Lt. Gov. Bill Halter (D), who is challenging Lincoln in a primary, raised $2 million in the first quarter. He raised that amount in a shorter time period, though, having entered the race late in the quarter.

Republican frontrunners Rep. John Boozman (R-Ark.) and state Sen. Gilbert Baker have yet to announce their first quarter totals.

Illinois state Treasurer Alexi Giannoulias (D) turned in his best fundraising quarter of the cycle so far, but he still raised about $1 million less than GOP opponent Mark Kirk in the Illinois Senate race.

Giannoulias's campaign just announced it raised $1.2 million in the first quarter in an e-mail to supporters. It's about twice what he raised last quarter, but it pales in comparison to Kirk's $2.2 million first quarter, which the congressman announced last week.

Kirk, who faced a less serious primary challenge, is also set to be in much better financial position for the general election, as he announced $3 million cash on hand. Giannoulias's campaign has not announced a cash on hand figure, but it was burning through serious cash to make it through a primary with former Chicago Inspector General David Hoffman in February, and it had less than $1 million on hand at the end of the year.

Giannoulias beat Hoffman 39-34. Since then, the Democratic nominee has dealt with a series of problems stemming from his family bank, which is on the brink of failure and, according to the Chicago Tribune, lent $20 million to a pair of convicted felons.

The late John Murtha's name is being thrown around in the Kansas Senate Republican primary.

Reps. Todd Tiahrt and Jerry Moran are currently battling over earmarks and Moran spokesman Dan Consto cited Murtha in an attack on Tiahrt

"It's interesting to see the very people running to replace Todd Tiahrt openly rebuking him and his signature issue: earmarks. As an appropriator, Todd Tiahrt has long championed some of the most egregious wasteful earmarks, including securing $400,000 for indoor tennis courts and voting against removing earmarks for Rep. John Murtha's 'airport for nobody,'" Conston told the Kansas City Star.

Tiahrt's camp fired back with a pointed reference to another famous earmark. "Did Moran also forget about the McPherson Opera House earmark he requested and, without the slightest hesitation, accepts credit for securing? Perhaps Jerry Moran is distorting the truth to keep people from looking at his record of raising taxes," the Tiahrt camp said.
