Hillary Clinton, Joe Biden and even socialist Bernie Sanders would crush Donald Trump, poll finds

Bombastic US billionaire Donald Trump handily leads all fellow Republicans in the 2016 presidential race, but Hillary Clinton and other Democrats easily trump him in head-to-head matchups, a poll said.
Trump plunged into the crowded Republican nomination battle last month, and has since uttered insults about Mexican immigrants and caustic jabs at rivals that have kept campaign media attention focused squarely on the trash-talking real estate mogul.
He now leads the 17-candidate Republican field with 20 percent support.
Following him were conservative Wisconsin Governor Scott Walker with 13 per cent and former Florida governor Jeb Bush, the son and brother of two presidents, with 10 per cent, according to results of a national survey released Thursday by Quinnipiac University.
No other Republican topped six per cent.
Trump’s negatives are sky-high, however. He led the “no way” list, with 30 per cent of Republicans saying they definitely would not support him.
