Be careful what you wish for ...

The great Mark Twain said, "It is better to keep your mouth closed and let people think you are a fool than to open it and remove all doubt." This should also be written somewhere on the first page of the McCain/Palin playbook for this campaign ... but it clearly is not.

Many commentators and reporters have criticized the Republican campaign for keeping Sarah Palin on an extremely short leash. She was, until recently, uttering no public remarks except for her standard stump speech (lifted almost entirely from her GOP convention speech), and she was criticized greatly for that.

Now it appears that we should have appreciated what we had when we had it, because the more she talks, the worse it gets. Her interview with ABC's Charlie Gibson was pretty bad, but her interview with Katie Couric of CBS was an unmitigated disaster. At this point, even the sound of her voice is becoming like nails on a chalkboard.

With every word out of her mouth, Sarah Palin demonstrates her lack of fitness for the vice presidency.
