Ramesh Ponnuru explains to National Review Online readers why he believes former Massachusetts Gov. Mitt Romney should get the Republicans’ presidential nomination.

Romney isn’t merely the candidate who is likely to win the Republican primaries. He’s the candidate who should win them. That’s why he’s likely to win.

We all know the knocks on Romney. His health-care plan in Massachusetts was Obamacare in one state. He’s a flip-flopper. Inauthentic. His conservative detractors say he’s the establishment/moderate candidate — or worse. (Actual Thanksgiving conversation in the Ponnuru home: Conservative brother-in-law: “So, which of these characters are you supporting?” Me: “I think Romney’s the best of the bunch.” Him: “I didn’t know you were a Democrat.”)

It’s true that Romney took a sharp right turn when he moved from state to national politics. But it’s also true that in 2008 he was the candidate behind whom Rush Limbaugh and Mark Levin, among other conservative notables, said that the conservative movement should rally in order to stop John McCain from getting the nomination. He has not moved left since that time. His positions on policy questions are almost all the same as they were then. On a few issues he has moved right: He now favors a market-oriented reform to Medicare, for example.

If Romney was to McCain’s right then, he is still. He’s to George W. Bush’s right, too.
