Whatever happened to Kansas?

Governor Sam Brownback promised that massive tax cuts would be "a shot of adrenaline" to the Kansas economy.  Other states have been watching. Five years later, it's shrinking instead of growing; school funding, roadwork and other services have been delayed or de-funded. Last week, fellow Republicans in the legislature overturned Brownback's veto and increased taxes again. We look at the consequences of an experiment in "supply-side economics" — a strategy that's still alive and well in Donald Trump's Washington.
