Update on celebrity politicking: One-time singing sensation Barbra Streisand has come out against the recent Supreme Court ruling giving corporations the legal right to make political contributions as she does. In a widely-overlooked item on Huffington Post this week, Streisand complained that the overwhelming 2008 “historic victory” of Barack Obama “was a mandate for change,” as was the awarding of overwhelming congressional majorities to progressive Democrats. But, according to Streisand, who says she’s been a longtime supporter of free speech, progress in Washington has been stymied not by political infighting but by big money.
