Deroy Murdock‘s latest column posted at Human Events documents the political split personality that plagues former Massachusetts governor and Republican presidential candidate Mitt Romney:

“Government under President Obama has grown to consume almost 40 percent of our economy,” Pro-Enterprise Romney said June 2. “We are only inches away from ceasing to be a free-market economy.”

“I support the subsidy of ethanol,” Rent-Seeking Romney said May 27 in Iowa, however.

Four days earlier, former Governor Tim Pawlenty (R – Minnesota) bravely opposed ethanol subsidies in Iowa. Nonetheless, Romney bear-hugged this boondoggle — weeks before the Senate voted 73-27 on June 16 to terminate the ethanol tax credit.

“I believe the world is getting warmer, and I believe that humans have contributed to that,” CO2-Fighting Romney said June 3. “I think it’s important for us to reduce our emissions of pollutants, of greenhouse gases, that may well be significant contributors to the climate change and global warming that you’re seeing.”

“Good for Mitt Romney,” former Vice President Albert Gore, Jr. wrote June 15. “While other Republicans are running from the truth, he is sticking to his guns in the face of the anti-science wing of the Republican Party.” …

… “Ronald Reagan is…my hero,” Reagan-Loving Romney said in 2005.

“I was an independent during the time of Reagan-Bush,” Reagan-Bashing Romney said in 1994, while running against the late Senator Edward Moore Kennedy (D – Massachusetts). “I’m not trying to return to Reagan-Bush.”

For a change, Republicans should heed a top Democrat. Like the proverbial busted clock that is right twice daily, Senate Majority Leader Harry Reid of Nevada was correct Tuesday when he said about Willard Mitt Romney: “The front-runner in the Republican stakes now? Here’s a man who doesn’t know who he is.”
