Picked up some food for thought from Paul Krugman's 3/19 post in his blog, "Conscience of a Liberal" - "I'm prepared to change my views when the evidence warrants. Are you?"
We often tend to crucify politicians for flip - flopping or for reneging on a campaign promise . Not fair, if the evidence warrants a change of mind. Of course, the key to whether a change in views is warranted by new evidence, is the quality of that evidence. Therein lies the problem. If the evidence is tainted, all bets are off. Who makes that determination? You and I of course. Let the debates begin!
