ROUGH CUT (NO REPORTER NARRATION) A series of protests interrupt a Donald Trump rally in St. Louis, Missouri with the Republican front-runner saying they add flavor to his campaign for the presidency. "Isn't this better than listening to a long boring speech, you can hear that from the other candidates, they don't say anything anyway," Trump said. His comments come ahead of Republican primaries in five states - including Florida and Ohio - on March 15 which will be critical for Trump to cement his lead, and to determine whether U.S. Senator Marco Rubio of Florida and Ohio Governor John Kasich will be able to continue with their increasingly long-shot candidacies. Trump's nearest rival in the race is U.S. Senator Ted Cruz of Texas. Trump's controversial campaign has led many Republican establishment figures to call for an all-out effort to prevent him from winning the nomination - an effort that Carson said would fracture the Republican Party and ensure a Democratic win in November. Next Tuesday's voting will be a pivotal point as candidates chase the 1,237 delegates from primary contests needed to win the nomination. Trump has 459 delegates, followed by Cruz at 360, Rubio at 152, and Kasich at 54, according to the Associated Press.
