Democratic presidential contenders Bernie Sanders and Hillary Clinton sparred in a debate on Sunday over who had the best chance to beat Republican front-runner Donald Trump, and mocked the level of discourse in the Republican White House race.<br />Near the end of a Michigan debate that featured sharp clashes over trade and the auto industry bailout, as well as a lengthy discussion of religion, Clinton and Sanders both said they could not wait to face the brash billionaire in the Nov. 8 election to succeed Democratic President Barack Obama.<br />"I think Donald Trump's bigotry, his bullying, his bluster, are not going to wear well on the American people," Clinton said.<br />"We have to end the divisiveness, we have to unify the country."<br />"We are, if elected president, going to invest a lot of money in mental health," Sanders said, then cracked a joke.<br />"And when you watch these Republican debates, you know why we need to invest in mental health."
