Rep Brady and Speaker Ryan didnt write a tax cut bill, but instead wrote a winners (corporations) and losers (millions of middle class) bill. The current bill is nothing like the Reagan tax cuts. It is a horrible bill out of the pit of Hell.
This bill could be more problematic for Republicans than just being a bad bill. It is pitting conservatives against each other. Look at how many here on FR are disparaging those who won’t get a tax break, as long as they get theirs.
