Cable networks are obsessed with "gets" -- interviews with big names -- before the other networks get them. Fox News is not going to be able to handle four or eight years of being blackballed by Democrats in power.
Interesting point, but it says more about the heavy tactics of the Dems than it does about FOX news. After all why would the party of "tolerance" and advocates of our rights (including free speech) be opposed to going on the most watched cable news network? The only possible reason is to try, as you said, to black-ball them in order to force them to speak the way they want... that goes against everything the Democrats keeps saying they stand for, and only bolsters the claims about Democrats that the Republican's make: i.e. They are only for free speech as long as it is speech that agrees with them and they will try any heavy-handed tactic to get conformity that they can.
As for the notion Fox News is "straight down the middle," I hope you're posting from a state where medicinal marijuana is legal. Otherwise I may have to turn you in and confiscate your medicine.
Not at all, they lean to the right. Not rabidly the way MSNBC leans to the left... but they DO lean. However all in all they do attempt to be fair in the fact that they have many liberals that appear regularly, and most opinion segments do manage to keep a balance of opinion.
Believe it or not, as much as I like him, my biggest beef is with Brit Hume. He is supposed to be a news anchor. He tends to wear his political leanings too much on his sleeve as he is reporting. Not so much in what he says, but usually the tone in which he says it. I would like to see them keep him, but get someone a little more neutral, or at least better at keeping their opinions hidden during reporting. And don't give the anchor a spot on the opinion programs.
All in all though... I would say that the Dems HOPE FOX will crumble under their boycott... but it is far from a sure thing. Fox is big; it is watched by many more than watch the other channels; and it is liked by many. The Dems need to be careful that they aren't perceived as trying to stifle dissenting opinions. Most American's that aren't blindly partisan to the Left won't take kindly to that perception.
