LOL.... Don’t believe everything you read no matter the forum. The announced speakers have been on the CPAC 2013 website for sometime now. I think they were added as they accepted. There were some media articles about Palin’a acceptance on 2/18 I know for sure.
I used to be on all the mailing lists of conservative groups. But since the recession of ‘08 (thanks Obama!), I haven’t been able to contribute - hence I’ve been dropped from their mailing lists.
