Poll: Clinton tops Trump in general election

CNN reports:

Hillary Clinton would beat Donald Trump in a general election match-up if the election were held today, a new poll shows.

Clinton beats Trump, 49% to 39%, head-to-head. She would be neck-and-neck with other GOP contenders -- including former tech CEO Carly Fiorina (45% to Clinton's 44%), retired neurosurgeon Ben Carson (46% to Clinton's 45%), former Florida Gov. Jeb Bush (44% to Clinton's 45%).

But if Vice President Joe Biden runs for president, he'd enter the race as the most popular presidential candidate, according to the NBC News/Wall Street Journal survey.

Clinton's favorability rating is underwater: 39% of voters view her favorably, while 47% say they see the former secretary of state unfavorably.
