Saturday morning roundup

Expecting a lot more updates on the various potential candidacies today and tomorrow.
–The Globe’s Michael Levenson offers an update on the field for the Massachusetts 10th Congressional, and notes that Democrats are definitely worried about the possibility of losing the seat.
–The Herald’s Hillary Chabot and Dave Wedge report that Democrats are committed to retaining Delahunt’s seat, and believe they have a strong bench in Keating and O’Leary.  The NRCC, meanwhile, is already noting O’Leary’s vote in favor of the sales tax and the fact that Keating lives outside the district.
–The Cape Cod Times reports that Massachusetts Secretary of Energy and Environmental Affairs Ian Bowles, who ran for the 10th Congressional in 1996, will not be a candidate in 2010.
–Following the other major announcement yesterday that State Senator Susan Tucker will not seek re-election, the Eagle Tribune reports that all sorts of candidates are emerging.
–In today’s Globe, Robert Weisman reports that Massachusetts health insurers have submitted rate hike increase requests of 8-32% to the state insurance commissioner.  This will be the first test of Governor Patrick’s new policy of reviewing all hikes above 4.6%.
–The Springfield Republican reports that a fourth Republican candidate has pulled papers to run for State Senate’s Hampden district seat.  Incumbent State Senator Stephen Buoniconti still has not said whether he will seek re-election or run for District Attorney.
–Reid Wilson writes in the National Journal about the Cahill/Baker dynamic, and the debate over which of the two is the actual conservative.
–And apparently 20 or so Tea Party activists protested outside a Nancy Pelosi fundraiser at the Liberty Hotel in Boston yesterday.
More to come.
