Charlie Wilson, a Democrat who represented eastern Ohio in the U.S. House of Representatives for two terms after winning a write-in campaign, died April 14 at a hospital in Boynton Beach, Fla. He was 70.

The Ohio Democratic Party announced Mr. Wilson’s death and reported the cause as a stroke.

Mr. Wilson served in the Ohio House of Representatives from 1997 to 2005. He then served two years in the Ohio Senate.

Mr. Wilson won his first congressional campaign in 2006 as a write-in candidate, filling the seat vacated when Democrat Ted Strikland became governor. He had failed to gather enough petition signatures to qualify for the state’s primary, requiring him to run as a write-in for the 6th Congressional District, stretching from Youngstown’s southern suburbs to the tip of the Ohio River near Portsmouth.

Mr. Wilson, who represented a coal-heavy district, served on the House Committee on Science and Technology. He lost bids for Congress in 2010 and 2012.

Charlie Wilson was born in Martins Ferry, Ohio, on Jan. 18, 1943. He owned several small businesses throughout the Ohio Valley. He attended Ohio University in Athens, and while still in college, he worked as a UAW member on the assembly line at the Ford Automotive auto plant in Lorain.
