WEST DES MOINES, Iowa - It's the No. 1 question headed into the Iowa caucuses: Does Donald Trump merely have fans, or does he have supporters who will mobilize come caucus day?

The definitive answer won't arrive until the night of Iowa's leadoff caucuses on Feb. 1.

But interviews with dozens of voters, political operatives, party leaders and campaign volunteers in the past week paint a mixed picture of Trump's efforts to lock in votes.

Questions about Trump's turnout effort are magnified by his place alongside Texas Sen. Ted Cruz atop preference polls in Iowa.

Republican leaders in the state largely agree that Cruz has the most powerful get-out-the-vote operation among the GOP candidates for president. Those same observers are mixed when describing what Trump has put together.
