For my taste, there is no better clearinghouse for the latest in political minutiae than Crooks And Liars. I visit it frequently. They are always good at getting up the latest video footage of republican fuck-ups. They are funny and good at exposing political hypocrisy. They also provide me with Daily Show highlights in case I missed it the night before.
Still, when it comes to dead-on political analysis, few do it better than my pal, Vikki. She puts any of the current pundits or op-ed writers to shame.
