Two words:
McCain-Feingold.
The fundamental difference between McCain 2000 and McCain 2008 is that he put his name on a law that forbids people from speaking out against their congressman within 60 days of an election.
That’s what I told the exploratory committee volunteer who called me up; I would absolutely not support McCain for president based on the BCRA.
“Even against Hillary Clinton?” she said BOO!
“What’s the difference?” I said.
How does that make you feel, Senator? You engender the same response in a former supporter and a former money donor as Hillary Clinton does.
