Topeka Democrat Ann Mah kicked off her campaign for the Kansas House Monday.
Mah served in the House for eight years before losing to Topeka Republican Ken Corbet by only 21 votes last November.
Mah was the Legislature's most vocal critic of Secretary of State Kris Kobach. A political action committee formed by Kobach backed Corbet.
After the 2012 election, Mah fought successfully in court to obtain the names of voters whose ballots had been set aside by election officials, in hopes of contacting them and helping them correct problems.
But this year, legislators changed state law to bar the release of the names of provisional voters.
