Perhaps you should try some spelling variations:
"Iowa's 8th congressional district" » "Iowa's 5th congressional district", "Iowa's 8 congressional district", "Iowa's _ congressional district"
"Iowa's 7th congressional district" » "Iowa's 5th congressional district", "Iowa's _ congressional district", "Iowa's a congressional district"

You may be able to get more results by adjusting your search query.

• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"Iowa's 8th congressional district\") OR (\"Iowa's 7th congressional district\"))".
• Removing quotes may allow a broader search: (( Iowa's 8th congressional district ) OR ( Iowa's 7th congressional district )).
• Adding a wildcard symbol may retrieve word variants: (("Iowa's 8th congressional district") OR ("Iowa's 7th congressional district"))*.
