Further evidence it's an election year: One of the biggest unions in the country, Service Employees International Union (or S.E.I.U.) is teaming up with MoveOn.org and Amnesty International to expand its campaign against private equity firms. (This is the same group, as you may recall, that staged protests outside the homes of KKR's Henry Kravis and Carlyle Group's David Rubenstein last year.) They've even roped in comedian Lewis Black, who's now appearing in commercials to rail against buyout firms for downsizing companies, taking on too much debt, and treating employees like numbers on a spreadsheet. Cute! Kinds of sounds like Viacom, the company that signs Black's paycheck, too!
