The conclusion was “probably not.”
I tend to agree, but not for the reasons mentioned in the article.
The tax cut won’t go into effect until 2018. Which means that the effects of the tax cut won’t be felt by most people until April 2019. Whatever the impact of the policy—good, bad, or indifferent—its actual consequences won’t come about until well after the 2018 election.
But somehow in a 1500-word article about whether the tax bill would help the GOP in 2018, the fact that its impact would happen after the election never seemed worth mentioning.
As Hanson would say, politics is not about policy.
Why deny the obvious, child?
 Except for those who estimate taxes quarterly, which is only about 10% of the population.
