The Liberal blogs, with the Daily Kos at the top of the list, are all having a fit that the Democratic candidates are appearing on Fox News. For them, the concept of freedom of speech ends when it is speech they don't agree with. It's funny how they don't even try to cover up the fact that when it comes to Fox News they act like fascists who believe Fox News has no right to exist.
The other interesting item to note about this is how quickly they turn on their own. We saw it with Hillary Clinton - when she wouldn't be strong-armed out of the race, they viciously attacked her with vile postings. It's like a bunch of spoiled children who are mad because they are not getting their way. Now that H. has appeared on Fox news, they are now calling him "weak" and his campaign spokesmen as "liars."
It's clear that Kos posters and other liberal bloggers have a clearly exaggerated sense of self-importance. They refer to themselves as his "base," but a there are a lot of people in this country. A few thousand liberal bloggers barely comes close to being able to deliver a significant majority in an election. They failed with Howard Dean in 2004, but they still haven't realized the actual limited scope of their influence. If anything, they have begun to marginalize themselves with hateful postings and profanity-laden insults. These are the types of things that will never be mainstream. The candidates are smart enough to realize this, and have intelligently looked beyond this childish, scornful, self-ascribed "base," and made steps to appeal to those of us in the real world.
