Democratic presidential nominee Joseph R. Biden held an 8-point lead over President Trump in a national poll taken immediately after last week’s Republican National Convention.
Mr. Biden held a 51% to 43% lead over Mr. Trump, according to the Morning Consult poll released on Tuesday — the same margin compared to polling taken immediately before the Democratic National Convention.
Mr. Trump got a bit of a convention “bump” in the daily tracking numbers right after the Republican National Convention concluded on Thursday, but that boost had dissipated by Sunday.
Mr. Biden also led Mr. Trump in a number of battleground states, according to polling conducted from Aug. 21-30.
The Democratic National Convention was held Aug. 17-20 and the Republican National Convention was held Aug. 24-27.
