Vermont Senator Bernie Sanders campaigned this weekend with fourth district congressional candidate J.D. Scholten (SHOHL-ten), with stops in Ames and Fort Dodge on Sunday.

Iowa’s fourth congressional district has a 70-thousand voter registration advantage for Republicans, but Sanders suggested intense interest among younger voters could spur record levels of voter turn-out.

Congressman King tweeted about Sanders this weekend, suggesting Sanders’ vision was akin to socialism in Venezuela and the former Soviet Union.
