A few thoughts:
Democrats have been running Denver for decades. If their ideas and policies were effective, why the high cost of housing now? Did they fail to plan?

I think the Democrats running Denver secretly LOVE high housing prices because it brings in more tax revenue. 

Instead of the same old rob Peter to pay Paul tactics that Democrats always resort to for affordable housing, do you think Democrats would ever consider freezing homeowner taxes so that they don't rise with the value of the home, and this would be a way to keep housing more affordable?
