ROUGH CUT (NO REPORTER NARRATION) STORY: Republican Presidential candidate Donald Trump stopped by a caucus Monday night, making a direct appeal to Iowans promising "to make America great again." Trump's ground-breaking White House campaign faces a moment of truth on Monday when Iowa voters begin the nationwide process of choosing a new U.S. president, with polls showing him in a tight battle with Cruz to be the Republican nominee. A Des Moines Register/Bloomberg Iowa poll on Saturday showed 45 percent of likely Republican caucus-goers were still uncertain and could be persuaded to switch to another candidate. The caucuses will be the first time Trump, a real estate tycoon and former reality TV star, has put his political appeal to the test.
