NEW YORK (CBS News) - Nationally, Donald Trump still has a double digit lead over his nearest competitor Ted Cruz, but his margin over Cruz has decreased. Now, 42 percent of Republican primary voters nationally would like to see Donald Trump as the Republican Party's nominee, while 29 percent support Ted Cruz, and 18 percent back John Kasich.
Last month, Trump's lead over Cruz was 20 points, but now it's dropped to 13 points. Trump's margin against Cruz has tightened among men, very conservative voters and those with incomes over $50,000.
Trump continues to receive support from a wide swath of Republican primary voters. He leads among men, with 44 percent, compared to 31 percent for Cruz and 18 percent for Kasich. He also leads among women, 44 percent, to 29 percent for Cruz and 19 percent for Kasich. Republicans, independents, white evangelicals, and non-college graduates also prefer Trump.
But Cruz leads among very conservative voters -- with 46 percent, compared to 40 percent for Trump -- and those who attend religious services weekly, and the race is close among those with a college degree.
