Last year Sen. John McCain's campaign finance reform bill was signed into law. I believe the law forbids political advertising 60 days before a general election. This means the tv networks could have their shows promote pro-Democratic themes. While, the GOP would be unable to run any political ads on primetime television during the crucial months of September and October.
This means the tv networks could have their shows promote pro-Democratic themes. Again, take a look at the top ten, top twenty shows and tell me with a deadpan look that "pro-Democratic themes" will be run through those shows previous to election time and will actually influence a voter to think, "You know, that storyline about the economy really motivates me to vote Democratic this election." Because the economy is all the Democrats have to run a serious campaign with right now.
