Grassley, in a speech to the crowd a couple of hours earlier, tied himself to the former president, showcasing that "President Trump and I were proud to deliver for the hard working people of Iowa and the United States, people just like you, policies that make a difference in the United States of America to continue America First."
Grassley will surely win and step down six months after. Not sure who would be best to take his place though. I like the way Grassley votes, and therefore I support him.
