Given what's transpired in recent weeks, this news is not terribly surprising:
Representative William Delahunt will not seek re-election to Congress, the seven-term Democrat will announce tomorrow, ending a nearly 40-year career in elected office and giving Republicans hope of capturing the seat, which stretches from Cape Cod to the South Shore.
"It's got nothing to do with politics," the Quincy Democrat said today. "Life is about change. I think it's healthy. It's time."
The 68-year-old lawmaker said he has been considering leaving the House for several years, but was talked out of it two years ago by the late Senator Edward M. Kennedy, who convinced his friend he should stay and help President Obama with his first-term agenda.
The tenth is MA's least-Democratic CD, going for Obama by just a 55-44 margin. (Kerry and Gore both posted similar numbers here.) Meanwhile, SSP numbers guru jeffmd estimates that Scott Brown absolutely dominated here, winning by about 60-40. So you can see why the GOP thinks it has a shot here. State Rep. Jeffrey Perry is already in the race, and former state Treasurer Joe Malone and state Sen. Robert Hedlund are weighing runs. Undoubtedly plenty of Dems will also give this contest some thought, and I'm sure we'll here more from the interested parties soon.
