One of the candidates in Iowa’s U-S Senate race is accusing the other of being partly responsible for the deaths of the 11 immigrants found in that rail car parked in Denison. Republican candidate Greg Ganske says his opponent, Democrat Senator Tom Harkin, supports providing welfare to illegal immigrants. Ganske says that’s one reason why folks in Mexico and other countries keep trying to smuggle themselves into the country. Ganske does not support providing welfare to illegals. Harkin campaign officials say Ganske has dipped to a new low by trying to tie Harkin with the tragic deaths of the 11 illegals who were found this week in a closed rail car after months on the rails.
