Lots of people change their names for lots of reasons. I'm not sure why the writer you're quoting felt the need to include that information, which isn't any secret. She was born in St. Petersburg, Russia, with the name Alisa Zinov'yevna Rosenbaum. That's common knowledge. She's still wrong in her philosophy, but pointing out her name at birth seems odd to me.

... Charles Krauthammer, ripping into the Republican/Libertarian’s take on ISIS and its relationship with Syria’s President Bashar al-Assad.

So, we know of at least one prominent Republican who’s not particularly a Rand Fan. Paul, of course, is anything but ignorant. Not many “ignorant” people graduate Med School and establish a successful practice as an Ophthalmologist. As an Ayn Rand ... disciple, Paul must hold to tenets that, in many instances, simply don’t apply to modern-day America. Even he is fleeing his “government butt out” philosophy.

He apparently realizes that, in changing his self-description of libertarian to libertarian-“ish.” Excuse me? He used the “ish” ploy during an April appearance on “Face the Nation” on CBS. He revealed a new-found affinity for the black population. “I’ve tried to say to the African-American population: “One, I’m going to fix the criminal justice system. Two, I believe in your privacy. And three, I believe in economic opportunity.”

On the Issues.org, quotes Paul as saying, “the federal government may have overstepped its role by making it illegal to impose racial segregation in the private sector.” He hastened to add that he wouldn’t want to be associated with those people. His apparent bottom line: “I love my black brothers and sisters, but let the Neanderthals be as racist as they wanna be!”

...at all the flip-flopping Paul is going to do as the primary progresses.

He's got a brand...ish...but no ideas or stances that aren't for sale.
