Small businesses were being held back by their tax burden. They wanted to invest more capital in their businesses, to scale up and hire more people. They had untapped opportunities in the market that they could not pursue because they didn't have the money that they would have if their taxes were lower.

Ratings agencies downgraded Kansas's bonds, forcing the
state to pay more in borrowing costs. Funding for state
school programs fell, and the Kansas Supreme Court ruled
the state government was not adequately funding schools.
Earlier this year, legislators grappled with a budget

In 2016, voters kicked out a handful of anti-tax
Republicans, in favor of challengers who backed higher
taxes, despite Brownback's opposition.
