In my column this week I deplore the fact that Mitt Romney gives a special place to Donald TrumpDonald John TrumpDems flip Wisconsin state Senate seat Sessions: 'We should be like Canada' in how we take in immigrants GOP rep: 'Sheet metal and garbage' everywhere in Haiti MORE, a visible voice of nut-case birtherism, at the Republican convention. Now, don't miss Justin Sink's story in The Hill, about Mitt Romney's sick joke about President Obama's birth certificate. Perhaps it is the Romney-Trump ticket after all. The great weathervane of American politics pays homage, yet again, to the sick politics of radical hate that has a privileged place at the seat of power of Romney's Republicans.

Mitt Romney should be ashamed. This is a man who claims that certain people and nations have a cultural superiority over other people and nations. Here is a man who says he likes to fire people. A man who demeaned Hispanics in his campaign against Rick Perry. Who tortures his own dog on a family vacation and uses elevators to lift his limousines to the top of his mansion.

What can one say about a man who aspires to the presidency who, instead of publicly rebuking nut-case birthers who question the Americanism of the president of the United States, courts them, imitates them, gives one of their leaders a special place at the Republican convention, and now tells jokes about the president's birth?

Here is what I say: If George Romney were alive today he would take Mitt Romney across his knee and spank him until his behind is red, for the kind of campaign he is running and the sick birther joke he is telling.
