Fundraising in the cycle before an election can give us signs of who is thinking about retirement or who is planning for a tough re-election. Looking through 2009-2010 FEC reports for 2012 Senate candidates contains some surprises about incumbents assumed to be likely 2012 retirements, such as Dianne Feinstein and Ben Nelson. Below you can find the fundraising, cash on hand, and debt of every incumbent senator up for re-election in 2012, with the exception of Kirsten Gillibrand, who first has to win a 2010 election and West Virginia, where we do not know who the incumbent will be.
I will arrange it by the amount (least to greatest) that the Senator has raised this cycle:

*Ability and willingness to self-fund
Scott Brown raised a huge amount of money in the run up to the MA special election, so much that he couldn’t spend it all. He had about 5 million left over immediately after the election, and has added an addition million to his campaign account since then. He heads into 2011 with the largest bank account of any senator up for re-election in 2012, other than Gillibrand, who has an election this year.
Incumbents Ben Nelson, Dianne Feinstein, Orrin Hatch, Tom Carper, and Olympia Snowe, all retirement possibilities in 2012, have raised decent amounts of money for their campaigns so far. Senators Daniel Akaka, Jeff Binjaman, Joe Lieberman, and Kay Bailey Hutchison, all retirement possibilities, are not raising much money. Hutchison has already announced her retirement, but she also announced her resignation two years ago. Dick Lugar and John Ensign, both considered very likely retirements, are still raising money. Herb Kohl is also considered a potential retirement in 2012, but it is difficult to tell from his fundraising reports, since he self-funds all of his bids.
