ROUGH CUT (NO REPORTER NARRATION) Donald Trump rallies the crowd in Sioux City, Iowa, as he makes reference to a recent national Republican presidential primary poll that has placed him behind Ben Carson. "We've had some amazing results and they continue to come in," said Trump. Got a little shake-up in Iowa. I don't know what's going on." Trump placed second with 22 percent of the support of those surveyed, trailing by less than the 6 percentage-point margin of error. The poll of 575 Republican primary voters was conducted Oct. 21 through 25. "But everybody said without question in every poll, this isn't just here, that the people that are with Trump are with Trump. They don't go anywhere, they're staying," said Trump, receiving applause from the crowd. The Republican candidates will meet on the debate stage on Wednesday night, providing a third opportunity for them to differentiate themselves. The national poll comes after three conducted in Iowa, the first state to vote in the primary process, showed Trump trailing Carson for the first time. For months, Trump had appeared impermeable to attacks from his Republican rivals in the November 2016 race for the White House. Despite criticism, gaffes and attacks, the New York real estate mogul held a tight grip on the first-place position in dozens of polls. There was one sign of encouragement for Trump in the poll. Of those supporting him, 55 percent said they had firmly made up their minds. Carson's supporters were less certain, with 80 percent saying it was too early to say whether they would ultimately vote for him.
