Republican congressman Tom Cotton (Ark.) delivered the party’s weekly radio address Saturday, making the case against Obamacare. The Harvard grad who signed up for combat and served both in Iraq and Afghanistan, is only a freshman, but unlike some freshman grandstanders in the Senate, he is making a difference and making his party stronger. The problem isn’t Republicans, he knows, but the president and his party who cling to their failed health-care reform. As he said on Saturday, “President Obama promised you could keep your plan if you like it. That’s not true. Five million Americans face cancellations, and the president’s own estimates predict that tens of millions more will lose their plan. Many more are losing access to their family doctors, specialists, and local hospitals. And the nonpartisan Congressional Budget Office projects Obamacare will cost the equivalent of at least two-and-a-half million full-time jobs.”

Cotton has consistently stood up for a muscular foreign policy and for adequate funding of the military, refusing to follow the isolationist fad that has enticed some on the right. On Ukraine, Cotton was an early and strong advocate for checking Russian aggression. Yesterday he reiterated his call for the president “to stand with the Ukrainian people and stand up, for once, to Vladimir Putin.” And long before many other lawmakers caught on, he called out the Iran interim deal as a “grievous, historic mistake.” I part company with him on certain issues like immigration reform, but he articulates his positions respectfully and ably. On this and other topics he is in sync with his red state’s voters.

In his Senate run against incumbent Democrat Mark Pryor, Cotton is leading by a small margin; Cotton will have an easy time tying Pryor to the Obama agenda, which is toxic in Arkansas. The Cotton-Pryor race is among the most critical if the GOP is to take the Senate. If Cotton pulls it off, the Senate, the GOP, U.S. foreign policy and the country will benefit.

So for all this, we can say, well done, Mr. Cotton.
