They've some sort of algorithm that matches politicians' quotes on topics.  You can see what any two politicians have to say on a particular subject, and click 'Spin' to see more on the same, or switch out one of the pols to compare to another.

Hmm.

Update: Actually this is a fun game!  Most of the politicians have many, many quotes associated with a particular issue, but with Sarah Palin you can take bets with your friends on how few she will have!  Sort of like a sad, inane version of the Price is Right...
