ROUGH CUT (NO REPORTER NARRATION)
Story: Front-runner Donald Trump said on Sunday (May 1) that he will have essentially sealed the U.S. Republican presidential nomination if he wins Tuesday's contest in Indiana, where he now holds a big lead over chief rival Ted Cruz.
A new NBC/Wall Street Journal/Marist opinion poll showed Trump with a wide lead in Indiana, 49 percent to 34 percent for Cruz and 13 percent for a third candidate, Ohio Governor John Kasich.
Trump, a 69-year-old real estate developer, sounded confident in an interview on "Fox News Sunday" when asked whether Indiana would basically end the long-running Republican race in his favor.
