MARIETTA — U.S. Rep. Bill Johnson, R-Ohio, has announced his re-election bid for the 6th District in 2016.

Johnson met Friday’s filing deadline for his seat and filed petitions showing support from the 18 counties in the district.

“I share the frustration of those who look toward Washington and see obstruction, inaction, and politicians of both parties voting for their political self-interests rather than for the good of those they serve,” Johnson said in a news release.  “President Obama, and those on far left and right political fringes, need to understand that while we may differ on policies, Americans shouldn’t view each other as enemies. Our enemies are the radical Islamic terrorists bent on taking us down, and our rivals are China, Russia, and others seeking to overtake our economy.”

Johnson, a Marietta resident, was first elected in 2010, after defeating incumbent Democrat Charlie Wilson for the seat by five points. He defeated Wilson in a 2012 rematch by six points, followed by a 19-point win over Democratic challenger Jennifer Garrison in 2014.

The 6th District, which voted narrowly for Republican candidates in 2000, 2004 and 2008 and for Mitt Romney by 12 points in 2012, was last rated +5 Republican by the Cook Political Report’s Partisan Voting Index, which gauges the competitiveness of Congressional races.

Two Democrats, Michael Lorentz of Belpre and Michael Davenport of Pomeroy, have filed to challenge Johnson.
