Women and minorities are oppressed in our society, according to the libs. They dont stand a chance without special laws, regulations, and special breaks through affirmative action in order to force the evil sexists/racists to make things more fair. It is the Democrats who provide these special breaks, and the natural home of such victims is the Democrat Party. The victims vote for the dims, who happily stay in power and dole out more and more favors in a spiraling cycle toward omnipresent government power and eventual bankruptcy.
When a member of a Victimhood Group jumps ship, it threatens to expose the fallicy of the basic foundation of Democrat power which would lead to the destruction of their party. Naturally, the Left is going to attack like cornered Rats and they will do everything possible to completely destroy their target.
Sarah Palin is the current day Clarence Thomas.
You, and Jeff Head nailed it, IMO.
