Donald Trump continues to lead his rivals nationally in the contest for the Republican presidential nomination.<br />Trump maintains the support of 34 percent of registered Republicans and Republican-leaning independents, compared with 25 percent for Sen. Ted Cruz of Texas, 18 percent for Sen. Marco Rubio of Florida and 13 percent for Ohio Gov. John Kasich.<br />In the Democratic race, former secretary of state Hillary Clinton still leads Sen. Bernie Sanders of Vermont, but her national margin is the smallest in a Post-ABC poll since the beginning of the campaign.<br />That Trump is a polarizing figure within the Republican Party is no surprise, and it's typified by the opposition among establishment and other Republicans that has intensified over the past few weeks.<br />The Post-ABC poll finds that more than half of Republicans and GOP-leaning independents think Trump is dishonest, does not understand their problems, lacks the right experience, and does not have the right personality and temperament to be an effective president.
