Harris’ momentum continues as she ties with Trump in these swing states

The good news keeps coming for Vice President Harris.

She has now not only made up ground in public polls in the swing states in her campaign for president, but has now actually taken narrow leads in three critical states that would put her at just enough electoral votes to win the White House, according to polling averages.
