Political Blog analysis -top 50

It was interesting to see the top 50 political blogs, some where kind of boring and did not grabbed my attention but with others I could pick up in the first few lines which political party they are with. They basically gave their view and opinion about a subject or on a political figure. I had a hard time figuring out the persuasive techniques to me a lot of them were sarcasm maybe their pitch tone changed when it came to something that the writer did not believed or agree with- but I don't think there wasn't much persuasion in them, they only thing that I think it may have encourage me to do by reading these blogs is that what we hear in the media is not necessarily always true and we need to search for a reliable source- so that we can have our own beliefs in it.
