GEORGETOWN, S.C. -- When Alexander the Great died at the age of 32 in 323 B.C., his once unbeatable army began a 2,900-mile withdrawal from India and headed home to Macedonia. As they retreated, the empire they had created collapsed behind them. To prevent pursuit, Alexander's royal cavalry and infantry dealt viciously with all internal dissent, destroyed cities and burned bridges. The Russians employed a similar scorched-earth tactic against Napoleon in 1812, as did the Red Army when Nazi Germany invaded the Soviet Union in 1941. It's a maneuver now being employed both domestically and internationally by Barack Obama.

The re-elect Obama-Biden machine has less sanguinary methods for dealing with discord in the ranks than the Macedonian army used 2,335 years ago. There are no goblets of poisoned wine, no toxic darts -- but the Obamians and Bidenites are no less effective. It took just hours for Democrats Cory Booker -- mayor of Newark, N.J. -- and U.S. Sen. Dianne Feinstein to recant after they had the temerity to criticize our Nobel laureate.

Mayor Booker told NBC's "Meet the Press" that he was "very uncomfortable" with attacks on Republican Mitt Romney's tenure at Bain Capital, and he said, "If you look at the totality of Bain Capital's record, they've done a lot to support businesses, to grow businesses." Less than two hours later, Hizzoner was on Twitter "clarifying" his remarks. Apparently, the social network message wasn't good enough for the O-Team. That night, in an eerie re-enactment of "purge confessions" filmed by Josef Stalin's NKVD, Booker went before cameras in a Web video, saying, "I encourage it, for the Obama campaign to examine (Romney's) record and to discuss it."

Feinstein, chairwoman of the Senate Select Committee on Intelligence, transgressed last Monday when she was asked about leaks of highly classified national security information. She responded: "I think the White House has to understand that some of this is coming from their ranks." Less than 24 hours later, the senior Democrat emerged from the White House woodshed to express regret for her words and penitently add, "I know for a fact the president is extremely troubled by these leaks."

At least Booker and Feinstein know what they did "wrong" and can avoid retribution by simply keeping their mouths shut. And though it may be tough to be a political crony of this president's, consider a few examples of how dangerous it is to an American ally.
