Republican gubernatorial candidate Rob McKenna has unveiled a plan that would spend an additional $1.7 million on the state's public education obligations and higher education through 2015.

McKenna's plan would take into account a series of expected savings, such as smaller government, more competitive state contracting and curbed health care costs, all ideas he's discussed before. The plan released Tuesday included a spreadsheet that puts dollar figures onto how much would go toward education in the coming years through 2021. McKenna also proposes a levy swap proposal to make education funding more consistent as required by a Supreme Court ruling earlier this year.

He said Tuesday that the plan takes into account that non-education spending growth is capped at 6 percent per biennium, while state revenue increases 9 percent per biennium.
