One of the most antagonistic and belligerent U S Senators, Tom Harkin, D-Iowa, is still his cranky old self and isn't holding back in his aggressive and confrontational mouthisms. What's a 'mouthism'? Well, it's something intentionally spewed from the mouth of a Harkin; not just any old Harkin. This one is a senator also named Tom from the normally and traditional conservative state of Iowa.
