CNN Poll: Biden’s lead persists post-conventions

New CNN Politics Poll Conducted by SSRS

After two political conventions unlike any the United States had seen before, Joe Biden maintains an advantage over Donald Trump in the race for the presidency, according to a new CNN Poll conducted by SSRS.
Among registered voters, 51% back Biden, 43% Trump. The difference in each candidate’s support when compared with a CNN poll conducted pre-conventions is within the poll’s margin of sampling error.
Both candidates boosted the share of their supporters who say they are voting more for their chosen candidate than against his opponent, though that figure is still higher for Trump than it is for Biden. For Biden, it’s up to 45%, from 38% pre-conventions, and for Trump, it’s now at 77%, up from 67% before the conventions.
Biden also shifted his favorability ratings into more positive territory (48% view him favorably now, 43% unfavorably) as Trump’s remained deeply negative (40% favorable to 56% unfavorable).
