Topeka ? Republican Kris Kobach has won re-election as Kansas secretary of state after championing photo ID and proof-of-citizenship requirements for voters.

Kobach won a second, four-year term in Tuesday’s election by defeating Democrat and former state Sen. Jean Schodorf of Wichita.

The key issues were policies Kobach advocated as the state’s top elections official.

A 2012 law enacted at his urging requires all voters to show photo ID at the polls. A 2013 law requires new voters to provide proof of their U.S. citizenship when registering.

Kobach said the policies prevent election fraud. Critics argued that they suppress turnout.

More than 20,000 Kansas residents’ voter registrations are on hold because they haven’t provided proof of citizenship.

Schodorf voted for both policies as a legislator but said Kobach administered them poorly.
