No, I am not nuts. From what I understand, she has been involved in corporate law and law firm management in Texas, as well as being president of the Texas bar. She has served on a city council (or was it a county council?). She has been involved in local and national politics. How many other justices have that experience? Believe it or not, it may take more intestinal fortitude to stand up for herself in those venues than the insular academic and judicial worlds where liberalism is the norm.
I forgot to address the issue of voting for Republicans again. Personally I don't care how you vote but I think you ought to wait and see how this nomination plays out in the coming weeks rather than burning your bridges behind you.
This is either a stupid nomination or a brilliant one. Time will tell. When either one becomes apparent, vote however you want.
