- if Obama wins the Democrat majority will certainly try.
They keep threatening, and at some point you must take them at their word.
Even if Senator Obama is against it personally, I cannot see him vetoing a
bill laid on his desk by Harry Reid and Nancy Pelosi. (of course, with the rough
ride McCain has had from conservative talkers over the years, he might be
inclined to sign it too

)
- when they do the backlash will be immense. Even left-of-center talkers
like Ed Schultz are warning against the attempt. It will just confirm the
worst accusations of Conservatives that Liberals have declared war on
free speech, and it will do more to energize them than anything else the left
could possibly attempt.
- the attempt will result in massive amounts of litigation, and given the current
composition of the Supreme Court, I suspect that the Fairness Doctrine will
ultimately be struck down in the end (after several years and tens of millions
of dollars).
If I am wrong get ready for a thousand or more "Rush Pirates" out there.
