Sen. Tom Harkin (D-IA) is leaving Congress and Republican Joni Ernst will take his seat. And regrets? He’s got a few. Namely that ObamaCare was probably too complicated because of efforts to placate various “centrist” Democrats (many of whom are gone now) and constituent groups. “We had the power to do it in a way that would have simplified health care, made it more efficient and made it less costly and we didn’t do it,” Harkin said. “So I look back and say we should have either done it the correct way or not done anything at all. What we did is we muddle through and we got a system that is complex, convoluted, needs probably some corrections and still rewards the insurance companies extensively.” That’s a pretty good summation, though he hasn’t exactly seen the light. Harkin insists Democrats should have done “single-payer right from the get-go or at least put a public option would have simplified a lot.” Somehow, we doubt that even more government control would have healed ObamaCare’s ailments.
