Rarely does a campaign come and go these days without the two warring sides claiming a TV ad is so outrageous that the stations must take the ad off the air.

And it’s no different in the initiative campaign of Governor Schwarzenegger versus the Democrat-union Alliance For A Better California. This afternoon, the Alliance demanded that TV stations yank the governor’s new Proposition 76 ad from the airwaves.

The 15-second ad features text and narration that claim that the budget initiative “will increase funding available to school districts.” Democrats and other interest groups argue that school funding will likely go down under Prop 76, not up.

(The non-partisan Legislative Analyst’s Office, by the way, has said that school funding might indeed decrease in fiscal tight times, but that the impact of Prop 76 in any given year is “uncertain.”)

This is actually the second “take that ad off the air” demand in just the past few days. Last week, the Schwarzenegger camp demanded that TV stations stop airing an ad opposing the teacher tenure initiative Proposition 74, for its claims that the measure would allow a principal to fire a teacher “without giving a reason or even a hearing.”

Even the wording of the criticism has been the same in the two instances, with both sides… the pro-Prop 74 folks and now the anti-Prop 76 folks… calling the other side’s ad “patently false.”
