Walter Cronkite on John Kerry: In the interests of your campaign and your party's desire to unseat George W. Bush, you have some explaining to do. When the National Journal said your Senate record makes you one of the most liberal members of the Senate, you called that 'a laughable characterization' and 'the most ridiculous thing I've ever seen in my life.' Wow! Liberals, who make up a substantial portion of the Democratic Party and a significant portion of the independent vote, are entitled to ask, 'What gives?' It isn't just the National Journal that has branded you as a liberal. So has the liberal lobbying group Americans for Democratic Action. ... What are you ashamed of?
