If you weren’t watching “The Young Turks” on Current TV this week, you missed triple-threat guest hosts Michael Shure, Tricia Rose of Brown University and Rolling Stone and BuzzFeed contributor Michael Hastings. There was a watershed moment in American history — President Obama’s endorsement of same-sex marriage — and a high school scandal that may dog Mitt Romney until November. Plus, one guest host does a killer Cenk Uygur impression and another dropped the all-but-F-bomb at the 11th hour. Be sure to tune in every weeknight at 7/6c for “The Young Turks” on Current TV. (Cenk will be back on Monday.)
