Proposition A is between casinos and Missouri school kids.

Supporters have gambled $16 million in advertising on the November ballot.  Their advertising claims Missouri schools will get more money if it passes.

But opponents said the advertising is misleading.

"Missouri casinos would see their taxes increase under Proposition A. It would provide over $100 million a year for schools in the state without a tax increase on Missouri residents. That's why it makes sense to vote on Prop A. New money for schools, no new taxes," Yes On A Coalition Spokesperson Scott Carton said.

The proposition would also eliminate Missouri's $500 loss limit on losing players, and would limit the number of casinos statewide to 13.

"They should make it two separate issues," Cynthia Tandy, who opposes Proposition A, said. "Do you want to drop the $500 limit and do you want to limit the amount of casinos in Missouri? If you have two separate issues so when I go to the ballot box I can vote on each one of those particular issues separately."

Meanwhile, though the ballot proposition specifically says the proceeds should go to education, other state laws could prevent that.

Opponents have filed suit in Cole County Circuit Court.
