The Des Moines Register poll of Iowa yesterday showed indies breaking strongly for Trump. They favor him by 14 points, 49-35. In 2016, IA indies favored Trump by 13 points, and he won the state by nearly 10 points.
I love this excerpt from that poll:
Among those who have already voted, Biden leads 55% to 32%. And among those who have yet to vote, Trump leads 64% to 28%.
