After a successful inaugural run last year, which brought renowned guests including Bill Clinton, Tim Russert, and Arianna Huffington to the Radio City stage, the Speaker Series is back, tonight kicking off with what is bound to be a lively debate between Bill Maher and Ann Coulter. Maher and Coulter are two incredibly outspoken pundits, whose views, while very occasionally overlapping (Maher was extremely critical of the McCain/Palin ticket, and Coulter famously said she'd prefer Hillary Clinton over McCain, deeming Clinton the more conservative candidate), are distinct enough — especially when it comes to religion — for this to potentially turn into a high-profile catfight. We can't wait.
