For the past eight months, a group of volunteer Iowa activists have been contributing to these Power Rankings and attempting to answer what GOP candidate is positioned to capture caucus gold if the event was tonight. The panelists have watched as candidates entered the race, surged to the top and then were found to be lacking the necessities that lead to a caucus win: consistent messaging, grassroots organization and activist energy and loyalty. The panel, which is comprised of our staff, academics, political consultants, GOP activists, local party officials and other state political reporters, is well positioned to gauge the strength of the campaigns in Iowa.
