Hillary Clinton surged past Donald Trump after her party’s convention, giving her a nine-percentage point lead in a head-to-head matchup, according to a CNN/ORC poll released Monday. Fifty-two percent of the survey’s participants backed Democratic nominee Clinton while 43 percent supported her Republican rival. In a similar poll before the Democratic convention, Trump led 48 percent to 45 percent, indicating a seven-point post-convention bounce for Clinton. In a four-way race including Libertarian candidate Gary Johnson and the Green Party’s Jill Stein, Clinton led Trump 45 percent to 37 percent, with Johnson at nine percent and Stein at five percent. Four of five post-convention polls have shown Clinton getting a clear bounce.
