I'd like to think that Democrats bring up the so-called Fairness Doctrine only to scare us conservatives, who then spend our time and money to prevent its reappearance--a reappearance the libs don't intend, anyway. I'd like to believe it's a political feint.
But Feinstein's rather intelligent. I don't agree with her a lot, but I can respect her. If she's talking like this, maybe there's something to worry about.
And yes, I do believe any so-called Fairness Doctrine would clearly be a violation of the 1st Amendment and would be struck down rather quickly and strongly. That doesn't mean we should tolerate its existence, even for a little while, though.
Apparently, though, not all Democrats are stupid enough to tout something so clearly unconstitutional.
