Why would Tea Party claim Ayn Rand ?
After all, Tea Party & much of Republican party, is a traditional, God-fearing bunch. Ayn Rand, as Fountainhead clearly shows, is anti-traditionalist. While liberals may want people to start paying taxes, conservatives pressure people to sacrifice themselves in different ways like in the so-called "ultimate sacrifice", i.e. joining the military and possibly dying in the war. And all those church donations... Besides conservatives fear the "brave new world" of stem-cell research & "playing god", whereas that is the way of the future in the medicine.
You can hear this pressure from conservatives in Tea Party, directed against the President Obama, that he is acting opposite to the will of the people. But why should he care about the will of the people, if he has his own vision ? Wouldn't innovations in laws, be akin to innovations in architecture ? And all this talk about "strict constitutionalism" is junk, according to Ayn Rand ? Or if laws can't be innovated on, because they are abstract ideas, so can't financial instruments, but I bet no follower of Ayn Rand will oppose financial innovations (as opposed to legal one). Would they ?
Holding laws of our "Founding Fathers" as ideals in law, as Tea Parties like to, is like holding colonial houses from the time of our "Founding Fathers" as ideals in architecture.
So, in summary, Tea Party & Ayn Rand are no more compatible, than Socialist Party & Ayn Rand (and maybe less)
