If Conservative economic and fiscal theory had any merit, then 2018 would have seen GDP growth along what was promised, and an increase in revenues collected by the federal government.
GDP was twice that of the eight years of Obamunism you moron.
Unfortunately, GDP growth for 2018 was the same as it was in 2015 without a tax cut.
LIE and LAME; GDP for 2015 was an anemic 1.004%. 2018 = 3.1%. 3.1% Greater than 1.004% Moron.
2015 01 3.3317%
2015 02 3.3395%
2015 03 0.9639%
2015 04 0.4002%
2015 Average = 1.0044%

Also unfortunately, federal revenues for 2018 were 2% less than 2017.
LIE and LAME. Revenues were slightly higher in 2018. So you're a liar and a MORON. Yay you!

So based on that empirical evidence, what conclusion can we draw from the results of one year of Russia Tax Cut Conservative policy?
Based on your lying and ignorance about everything, we can conclude that you really are a hyper partisan moron on steroids and no one should take your bullshit seriously.
