Palin endorsed no one in 2008.
Santorum endorsed Romney, Romney is Romney, Paul did not endorse Romney, and unless you know something about Gingrich endorsing someone, then you can quit giving out all the endorsements for Romney that you consider positive for him, and that you keep posting on thread after thread, in post after post, day after day.
Thanks. Maybe a Gingrich supporter knows if he endorsed anybody — maybe one of those who thinks that who you endorsed in the past is the most important thing.
