Two measures proposed for this year\'s ballot in Michigan appear to be in direct conflict. One would automatically give school districts, universities, and community colleges enough money each year to at least cover costs that rise because of the inflation rate. The other proposal would limit overall increases in state spending to a combination of inflation plus population growth. Opponents of the two measures say that if both were approved by voters, the state could be required to return more money to taxpayers while increasing spending on schools and colleges.
