Pipe Manufacturing Factory In Marietta, Ohio

MARIETTA, OH - OCTOBER 25: U.S. Sen. Rob Portman tours Pioneer Pipe while campaigning in the area on October 25, 2016 in Marietta, Ohio. Portman is leading Democratic ex-Gov. Ted Strickland by double-digits in the polls. Ohio has become one of the key battleground states in the 2016 presidential election with both candidates or their surrogates making weekly visits to the Buckeye State. Unlike other parts of America, Ohio has both a rapidly aging and declining population; it is also overwhelmingly white and has a high degree of residents without a college education.
