No Bump, Just Grind? Poll Shows DNC, RNC Conventions Changed Nothing

Just before the Democratic National Convention in mid-August, Joe Biden led with a 51% to 42% edge over incumbent Republican President Donald Trump.

Now, both conventions are over.

And according to CNN's poll of polls, Biden is still in the lead at 51% to Trump's 43%.

For Biden, the DNC was a smooth four days, in which he demonstrated that the doddering caricature of him painted by Trump was wrong.
