With Schuitmaker running for reelection in a different district in the 2014 election, Wenke announced that he would run for the 20th district seat in September 2013. In 2014, he switched to the Libertarian Party over difference with the Republican Party on gay marriage and issues surrounding taxation. Running in the general election against Democratic Party nominee Sean McCann and Republican Party nominee Margaret O'Brien, Wenke received less than 10% of the vote. His 7,000 votes were the most for a Libertarian candidate in Kalamazoo County history.
