Missouri U.S. House candidates hit the campaign trail without set districts or voters

Campaigning in front of a group of seniors in Brentwood, Mo., Democrat Ray Reed has no idea whether the people he's asking to vote for him will ever see his name on their ballot.

Brentwood currently sits in the 2nd Congressional District, represented by Republican Ann Wagner. It's the district Reed hopes to win in November, but thanks to a monthslong redistricting fight between Republicans in the Missouri legislature, Reed and other candidates are in the dark about the boundaries of their districts.
