John M. Palmer, American general and politician, 15th Governor of Illinois (b. 1817)
John McAuley Palmer (September 13, 1817 – September 25, 1900) was an Illinois resident, an American Civil War General who fought for the Union, the 15th Governor of Illinois, and presidential candidate of the National Democratic Party in the 1896 election on a platform to defend the gold standard, free trade, and limited government.

Palmer switched political parties throughout his life, starting out a Democrat. He became in turn an anti-Nebraska Democrat (against state sovereignty on slavery), a Republican, a Liberal Republican, returned to being a Democrat, then ended as a Bourbon Democrat. He said, "I had my own views. I was not a slave of any party," and added, "I thought for myself and [have] spoken my own words on all occasions."
