Hillary Clinton has rapidly expanded her lead over Donald Trump since the two presidential hopefuls were running neck-and-neck last month, holding a 12-point advantage over her Republican opponent in a new Monmouth University national poll.

Clinton leads Trump 46 to 34 percent in the latest survey of registered voters, marking a 10-point increase in support for the former secretary of state from a poll taken before both parties’ national conventions. Among likely voters, Clinton’s lead over Trump expands to 13 points – 50 to 37 percent.
