Lieberman

From The Washington Post:

The Connecticut Democrat "snubbed" the president's health-care entreaties and gave "aid and comfort" to the Republicans. Liberal activists arrested in a protest outside his office said "we blame Lieberman" for weakening the Senate majority leader's bill. Liberals said he made a "political decision early on to pander to the insurance industry." He shifted positions so much it was "like trying to hold quicksilver in your hands."

Sound familiar? Those quotations are all from the summer of 1994. The president he snubbed was Bill Clinton, the Republican he aided was Bob Dole, and the majority leader he weakened was George Mitchell.
