I think that you can get around any political ranking of found items by subscribing to daily Google (news) Alerts with the keyword(s) of your choice. All the daily news centered around that keyword, relevant or otherwise, will be brought to you. For example, if you used the keyword "Republican-In-Name-Only," you would get conservative stuff relating to Lincoln Chaffee, Olympia Snow, Susan Collins, and John McCain.
Snow = Snowe (not that I care about spelling THAT PARTICULR SENATOR'S NAME wrong, but people tend to notice these things).
