That is a horrendously incorrect framing of this election this November.
First of all, a vote for Harris is NOT "a vote for Democracy." She was very un-democraticly appointed to be the Presidential Nominee. So I don't see how voting for an un-democratically appointed candidate, is a vote for Democracy.
As for Trump, there is really not much to defend. But he does not have power to turn our nation into Fascism, nor does he have the support. So the wild fears about the permanent end to our country that would come with a Trump re-election are completely fictional.
