Donald Trump's daughter-in-law says Kamala Harris polls as bad as Biden

"Millions of Americans came out in those primaries and voted for Joe Biden to be their nominee on the Democrat side. If they decide right here in the 11th hour to plug somebody else in, and it's not Kamala Harris, I can't think of a bigger assault to our democratic process than doing just that. But let's see what they do. Regardless if it's Joe Biden [or] Kamala Harris, Donald Trump's polls show us right now that the American people are behind him," Lara Trump told Fox News.
