Never mind the rumors about Sam Brownback endorsing Rudy Giuliani for president; the Kansas senator decided to back John McCain after all. Cyclone Conservatives has a good write-up here, or you can read the Des Moines Register's coverage here. I liked Mike Huckabee's comment in the Register:

Huckabee, campaigning Wednesday in Cedar Falls, said he would have liked Brownback's endorsement, but “we're getting a lot of Brownback's supporters. If I had a choice between him and his supporters, I'll take his supporters.”

Don at Cyclone Conservatives says he knows former Brownback supporters who have switched to Huckabee or Fred Thompson. The person I know who interned at the Brownback campaign plans to volunteer for McCain. It will be interesting to see how it all shakes out. 

Meanwhile, Bob Vander Plaats, who's chairing the Huckabee operation in Iowa, says they are not worried about missing out on the endorsements of Brownback or evangelical Pat Robertson, who recently backed Rudy Giuliani.
