For Mike Huckabee and Rick Santorum – who won Iowa’s last two caucuses on the strength of evangelical voters – doing well this weekend at the Iowa Faith & Freedom Coalition’s gathering is a must.

“Santorum and Huckabee are the two who really have the most at stake,” said Sam Clovis, a Sioux City social conservative who placed second to Joni Ernst in Iowa’s 2014 GOP Senate primary. “Between Huckabee and Santorum, they need to come back and recapture some of that magic they had in ’12 and ’08.”

Altogether, nine Republicans likely to make 2016 presidential bids will appear at Saturday’s Faith & Freedom Coalition Spring Kick-Off in Iowa. The subtext for the event will not be subtle: It is taking place at the evangelical Point of Grace megachurch in Waukee, a Des Moines suburb, and will attract the leading activists from Iowa’s social conservative community.
