it's also from May, which -- last time i checked -- is before August on the calendar. and also has nothing to do with the actual numbers that Kansas is actually short in their actual budget. when other "red" states like Nebraska, Missouri and fucking Mississippi are saying your state's policies are a failure, there is something horribly wrong with them....
It does point out that taking the information from the news articles and assuming it is all due to the tax reforms isn't necessarily the correct interpretation to apply - and it is just an interpretation.
It could be right, for myself I would be interested to see the relative performances of the other states mentioned for the period before Kansas implemented it's changes, and after it implemented it's changes.
Not meeting budget is an issue, but there can be many reasons why budget isn't being met, it could be that the budgets are just being too optimistic in general - if Kansas is overstating it's budgets, then regardless of anything else it is going to keep looking bad.
Other metrics could be useful, GDP or something else on a per capita basis, to see what impact the tax reforms have had, just comparing actual taxes to budget seems a very blunt instrument. If they hadn't implemented the changes, they may still be missing budget.
