The candidates in an Arizona legislative race that could decide control of the Senate clashed on this weekend's "Sunday Sunday Off" over funding schools and cutting taxes.

Republican State Rep. Kate Brophy McGee and Democratic House Minority Leader Eric Meyer are both leaving the House to compete for the open Senate seat in Legislative District 28, covering north and north-central Phoenix and Paradise Valley.

The LD 28 legislative race is one of four November races whose outcomes could shift the balance of power in the Senate from Republican to a divided chamber, split 15-15.
