GREENFIELD: In Washington, it’s all about partisan gridlock and nothing gets done. Working with local governments, I learn to do things differently in Iowa. When a pothole needs fixin’, it’s not a partisan problem, it’s a problem that needs to be solved. Our bridges are in the worst condition in the country. These aren’t Republican or Democratic bridges; they’re bridges that need to get fixed. I’m Theresa Greenfield and I approve this message because we’ve had enough of gridlock, it’s time to get moving.
