Lotta e-mailers taking issue with me on the idea that there’s a gaping market hole for a left-wing news channel because what are CNN, MSNBC, etc? I’m not talking about mushy liberal. I’m talking serious Left — Air America left, Daily Kos left. I don’t know how big a market hole there is, but I guarantee you it’s bigger than the audience that will watch Current (or MSNBC, for that matter).
