What is it with Democrats and the urge to tax everything–even things that breathe? They have a particular fascination with taxing carbon dioxide–the building block of life and the substance every living thing breathes out with every breath. The latest Democrat who wants to tax CO2 is Pennsylvania Senate Minority Leader Jay Costa, Jr. (from Pittsburgh) who introduced Senate Bill (SB) 15. Costa falsely calls it a “cap and invest” plan. In reality and normal plain English, it’s a tax plan–taxing natural gas-fired power plants.
