In the wake of the American Health Care Act’s collapse, the blame game is in full effect, both within the Republican party and outside it. Trump’s attacks on his own party’s key factions and failure to bring them around to his health-care bill don’t suggest that he’s going to bring together a coalition of lawmakers behind any sort of tax plan. Nor does the vote-counting ability of the current Republican leadership.

You need to pick off stakeholders

One of the most incredible things about the Republican health-care bill was that it won over none of the interests involved in the health-care business. Compare that to the Democrats’ efforts on Obamacare to diligently win over hospitals, insurers and even drugmakers with a deal: You drop your costs, we’ll provide you more customers. This bargain hasn’t always worked out as well as either side hoped, but it resulted in a law being enacted and insurance coverage expanded. On tax reform, depending on what direction the GOP decides to go, it will be important to get some powerful interests behind the bill. But the challenge of doing so is the same challenge as many government reforms: The benefits are far more diffuse than the costs, which means those protecting the status quo will have an easier go of it. Consider a choice to close a $318-million tax loophole and give every American a $1 tax refund. Which side will fight harder for their favored outcome?

You need better politics

While taxes are a perennial source of complaint, they rarely crack the top list of issues motivating voters.   Indeed, most Americans favor higher taxes on the wealthy, not lower. Democrats will have a field day pointing out how much money Trump and his cabinet of billionaires will save from the GOP’s proposed tax plans compared to the average American, even as he proposes budget cuts. The plan to repeal the estate tax will be called something like the ‘Ivanka Intervention.’

As important, without repealing the Affordable Care Act, Republicans will find it difficult to pass a major tax cut without winning over a few Democratic votes in the senate to avoid a filibuster. While hardly impossible, it would likely require curtailing the size of the cuts and offering something, likely infrastructure investment, in return—a move that might anger the Republican right-wing. There’s a reason that the last tax reform, under President Ronald Reagan in 1986, was bipartisan, and the closest the US has come to repeating the feat in recent years was a grand bargain nearly struck between president Obama and House speaker John Boehner in 2011.
