The New York Times reports that one factor in Hillary Clinton's decision on moving to the Cabinet is a disappointment with the Senate:
The uncertainty, a week after Mr. Obama met with Mrs. Clinton in Chicago to discuss the idea of her leading the State Department, kept Washington spinning in feverish speculation about whether the two former rivals for the Democratic presidential nomination would team up. Mrs. Clinton was keeping counsel only with a tight circle of confidants, leaving even prominent veterans of the Clinton political operation guessing as to her intentions.
But driving her consideration, friends said, is a sense of disenchantment with the Senate, where despite her stature she remains low in the ranks of seniority that governs the body. She was particularly upset, they said, at the reception she felt she received when she returned from the campaign after collecting 18 million votes and almost becoming the first woman nominated for president by a major party.
"Her experience in the Senate with some of her colleagues has not been the easiest time for her," said one longtime friend who insisted on anonymity in exchange for sharing Mrs. Clinton's sentiments. "She's still a very junior senator. She doesn't have a committee. And she's had some disappointing times with her colleagues."
