Sneak Peek: Couric Sits Down with Palin

Today, Katie Couric sat down with Alaska Governor Sarah Palin for the third on-air interview with the elusive VP candidate since the Republican convention.

The interview will air tonight on the CBS Evening News. In the meantime, CBS producers have posted a brief clip from the interview on their Web Site.

First impressions: no scenic Alaskan backdrop (like with ABC's Charlie Gibson). And no letting down of her hair (like with Fox News' Sean Hannity). Also: much more pink clothing and increased chatter about another Great Depression.
