Writing quite moderately about Mitt Romney today, NYTimes opinion columnist Nicholas Kristof reviews past charges of flip-flopping candidates and reminds of us of Paul Tsongas calling Bill Clinton “a pander bear” in 1992—there are photos of Paul holding up a stuffed panda bear at campaign rallies. I don’t know who came up with the panda bear thing, but it stuck for a while and is remembered. Read Kristof here, and get the NYT if you want more.
