ST. PAUL — Minnesota senators are set to vote on a spending plan that devotes more money to preschool programs, financial aid for college students and allowances for caregivers for the disabled and elderly.

The plan to be debated Tuesday would draw the money from the remaining state budget surplus.

The Senate’s proposal is leaner than a companion House bill passed last week. The combined spending in the Senate bill is $209 million, or roughly two-thirds what the House plan allocates.

Specific spending priorities in the two plans overlap in some areas and differ in others.

Once the Senate passes its version, negotiators for the two chambers will begin working on a unified proposal to send to Gov. Mark Dayton.
