Palin's 'Collected Tweets'

Former Bush speechwriter Michael Gerson writes about the new Tea Party Republicans:

In the normal course of events, political movements begin as intellectual arguments, often conducted for years in serious books and journals. To study the Tea Party movement, future scholars will sift through the collected tweets of Sarah Palin. Without a history of clarifying, refining debates, Republicans need to ask three questions of candidates rising on the Tea Party wave:

First, do you believe that Social Security and Medicare are unconstitutional? This seems to be the unguarded view of Colorado Republican U.S. Senate candidate Ken Buck and other Tea Party advocates of "constitutionalism." It reflects a conviction that the federal government has only those powers specifically enumerated in the Constitution -- which doesn't mention retirement insurance or health care.

This view is logically consistent -- as well as historically uninformed, morally irresponsible and politically disastrous.
