While Republican frontrunner Donald Trump still needs more than 300 delegates to reach 1,237 — the magic number needed to secure the GOP presidential nomination — he has finally reached a key milestone in his bid for the White House: support from half of the country’s likely Republican voters. According to a new NBC News/SurveyMonkey national tracking poll released Tuesday, 50 percent of Republicans and Republican-leaning independents say they support the real estate mogul’s candidacy, compared to the 26 percent who support Texas Sen. Ted Cruz and the 17 percent who are backing Ohio Gov. John Kasich. Trump’s double-digit lead over his GOP rivals is one reason Cruz and Kasich banded together this week in an effort to block the brash billionaire from winning the GOP nomination.
