Two controversial ballot measures in Oregon are headed for defeat, but a third is too close to call right now, according to unofficial results posted on the Oregon secretary of state’s Web site.

Oregon voters have rejected an effort to limit the amount of time non-English-speaking public school students may be taught in a language that is not English. They also voted down a proposal to redirect roughly 15 percent of state lottery money away from schools and toward law enforcement. That would have amounted to a loss of about $200 million every two-year budget cycle.

But the fate is uncertain for a proposal to restrict political spending of unions. Results posted so far haven’t given either side a decisive victory. The measure would prohibit payroll deductions from public employees for organizations, including unions, for political purposes.
