The latest polling from Iowa, per Monmouth University’s survey taken 30 July-3 August, shows President Trump with a three-point lead over Democratic nominee former Vice President Biden (48 percent to 45 percent). The margin is the same in the Senate race, with incumbent Republican Joni Ernest leading Democrat challenger Theresa Greenfield. In the presidential race, Libertarian Jo Jorgensen is pulling 2 percent, “other” is at 1 percent, and undecided is 3 percent – equal to the margin between Trump and Biden. Iowa is considered a key battleground state. One of the most interesting details is the independent vote with 7 percent still undecided.
