McCain cannot stack the Supreme Court or any Court with wing-nut judges by himself. His nominees have to be confirmed by the Senate. A Senate that will almost certainly be controlled by Democrats, probably with an increased majority. Why should I have to worry about Roe v. Wade or any other core constitutional right? While the Democrats would inevitably have to compromise on some issues with a Republican president (just as Obama will have to compromise some to get legislation through the Senate given the unlikelihood of a filibuster-proof majority), surely a body that is controlled by the Democratic Party will fight for my right to control my body. And if they won’t, then why am I electing any of them to Congress?
