Almost everybody has gotten into the act today, bringing out a national presidential poll. Biden leads them all, but some readers might want to see how they compare.

Two unrated pollsters released surveys as well. Opinium has Biden leading by 13 points, and Qriously has Biden ahead by 5%.
The aftermath of the conventions basically showed that Biden had a bump of 0 to 1% but improved has favorable ratings by about 5%. Trump’s convention produced a 2% bump but little or no improvement in his favorable ratings.
Convention bounces almost always fade after a week. So to whatever extent these polls are measuring some improvement for Trump because of his convention, it will likely be gone next week.
Improved favorable ratings for Biden may improve Democratic turnout.
