I agree.
The only people likely to be angry over passage of the bill live in states that are blue anyway. The states with large, now non-deductible state taxes.
So I doubt the dems non-support for the tax bill will hurt their near-term reelection changes in those states, but the purple and red states should all shift further to the pubs.
The Dems are shouting that the tax cuts are actually tax breaks only for the corporations and the rich, and increases for everyone else. They base that on the true fact that taxes for the middle class will increase - they don’t mention the increase is in five years and not now.
They also fail to mention that the increases are required because the current tax reductions expire then and that they had an opportunity to make them permanent if they had supported broader expanded tax reform requiring at least 60 votes in the senate instead of the simple majority vote that passed this bill.
