Assuming State Senator Jack Hatch follows through on the gubernatorial bid he is exploring, one of Iowa’s most Democratic-leaning Senate districts will be open in 2014.

Yesterday former State Senator Tony Bisignano announced that he plans to run for Senate district 17. After the jump I’ve posted background on Bisignano, a district map, and the latest voter registration figures. I expect a highly competitive Democratic primary, since Republicans have no realistic chance of winning this seat.
