If Democrats try to pass a bill with the Excise tax, they will lose all support from Unions. Even thought the Excise Tax has been hyped into a nefarious implement of Union Busting (which it isn't), the political reality is that Union members believe it is. And there are other ways to solve the problem.
It appears that Obama's meeting with the Union Leaders was productive in both directions.

Negotiators are considering extending the Medicare payroll tax, which now applies only to income from wages, to cover some of the investment earnings of couples making more than $250,000 a year, and individuals earning above $200,000. That could make up lost revenue from dropping the high-wage income tax and scaling back a proposed tax on high-value insurance plans, which is strongly opposed by organized labor and House Democrats.
On another high-profile issue, the negotiators are discussing a hybrid of a proposed national insurance exchange contained in the House bill and the state-by-state approach favored by the Senate. House Democrats are pressing for a national system to apply pressure to the insurance industry after their proposal for a new government-run insurance option was ruled out due to opposition from Senate moderates.
This is good and shows both sides are willing to make something work here. And there is this good point that highlights there are plenty of non-union workers out there that should be considered as much as any union member:
Obama met with union leaders Monday, and one union official familiar with the discussions said labor leaders and White House staff also explored the possibility of exempting or delaying health plans covered by collective bargaining agreements from being subject to the tax. They also discussed possible carve-outs for state and government employees, many of whom are unionized.
But some union officials are concerned about any compromise that would appear to give unions special treatment. They want a fix that protects both union and nonunion middle-class workers from paying higher taxes on health plans.
While unions are important, Obama remembers that not every middle class worker is a union worker.
