The GOP faces 2 issues.
First, the Senators above are not committed.
Second, if a CBO report is true and the bill hurts the poor while increasing deficits, can the GOP afford to pass such a plan?
The Washington Post Reports:
The Senate Republican tax plan would give substantial tax cuts and benefits to Americans earning more than $100,000 a year, while the nation's poorest would be worse off, according to a report released Sunday by the nonpartisan Congressional Budget Office.
Republicans are aiming to have the full Senate vote on the tax plan as early as this week, but the new CBO analysis showing large, harmful effects on the poor may complicate those plans. CBO also said the bill would add $1.4 trillion to the deficit over the next decade, a potential problem for Republican lawmakers worried about America's growing debt.
By 2019, Americans earning less than $30,000 a year would be worse off under the Senate bill, CBO found. By 2021, Americans earning $40,000 or less would be net losers, and by 2027, people earning less than $75,000 a year would be worse off. On the flip side, millionaires and those earning $100,000 to $500,000 would be big beneficiaries, according to CBO calculations. (In the CBO table below, negative signs mean people in those income brackets pay less in taxes and are better off).
This tax plan may be a non starter with Senators like McCain, Corker, Collins and Johnson. The bill is simply bad for the deficit and bad for working Americans.
