These polls are well within the margin of error. Don't trust them.
The only poll that matters is your vote this election. Plan your vote now. Check to see if you weren't removed from the voter rolls and still registered. Make sure your polling location hasn't been eliminated. If you vote absentee make sure you mail it back weeks before it is due since Trumper postmaster general Louis DeJoy is doing his best not to deliver your ballots on time.
Trump got his ass handed to him by Kamala in his first debate. Can you blame him chickening out of a second one? This one, despite no fact checking by the mods Vance was free spew all the old lies about Trump's record. What's most damning is that he refused to acknowledge Trump lost the last election and unlike Pence as VP he would refuse to certify any election Trump loses, guaranteeing a Trump dictatorship and killing all future free elections. The death of our democracy in not so many words.
