Santorum and Huckabee, past winners, lag in Iowa

MARSHALLTOWN, Iowa - Once they were winners. Now, in some respects, they are the forgotten men. The winners of the last two Iowa Republican caucuses - Rick Santorum in 2012 and Mike Huckabee in 2008 - are running again this year. They soldier on, visiting evangelical churches, Pizza Ranches, coffee shops, senior centers and house parties, though the polling numbers suggest they are long shots.
