I have an article on the homepage today that raises, and attempts to answer, a question.
In 2000, Joe Lieberman had to move left on school choice, Social Security, and affirmative action to get on the Democratic ticket. After his shift in positions, he was aligned both with Al Gore, the presidential nominee, and with his party. McCain’s choice is going to be trickier, since on several issues he himself is not in alignment with his party. If he picks a vice-presidential nominee from the conservative end of the party, should he make that nominee profess agreement with him on global warming, immigration, stem cells, and the like?
