It's been quite a dry spell for Hillary on the endorsement front since Iowa. But she just picked up Sen. Patty Murray (D-WA).

Late Update: A few readers have written in to dispute that Hillary's had a dry spell and have provided lists of various minor officeholders who've endorsed her over the course of this last month. Rep. Waters (D-CA) endorsement yesterday was significant. But there's no ignoring the fact that Obama has put up a series of high-profile endorsements in January even during the period when she's been in the ascendent. Govs. Napolitano and Sebelius. Sens. Kennedy, Kerry, Leahy, Johnson, Ben Nelson, McCaskill, etc.

Later Update: I've just found out that Sen. Bill Nelson (D-FL) last night made official the endorsement of Hillary that had been expected for several days. Same overall picture applies though. Barack's been way out ahead in endorsements all month.
