Sen. Rob Portman might not have the tough re-election battle that was expected earlier in the cycle, but the Ohio Republican has continued to campaign vigorously across the state and on the airwaves.

That is apparent again Thursday, with a closing argument ad that a campaign aide said is backed with a $1 million buy.

In the ad, which is running statewide, Portman makes a direct appeal from an American flag factory in Ohio that produced flags used during the Battle of Iwo Jima and the Apollo moon landing.

The freshman senator has managed to stay well ahead of his Democratic challenger, former Gov. Ted Strickland, despite changing attitudes toward trade.

“People here and workers all across Ohio deserve a fair shot to compete. I’ll continue to stand up for them and to fight back against countries like China when they threaten Ohio jobs,” Portman says in the ad.

The term “fair shot” has been popular in Senate talking points, though often as part of Democratic messaging in what’s been billed as the “fair shot agenda.”

Portman’s supporters also reportedly sent mailers in October about the fight against Ohio’s opioid addiction epidemic saying, “Rob Portman knows we are stronger together.”

That line echoes in part a campaign slogan used by Democratic presidential nominee Hillary Clinton.

The Ohio Senate race is rated Republican Favored by The Rothenberg & Gonzales Political Report/Roll Call.
