The fate of the tax reform bill is the fate of the modern Republican Congress. A win will bring economic growth, millions of new jobs, higher incomes, and a great increase in national wealth as the stock market climbs yet higher. This will bring optimism and reduce the grumpiness of the lousy sluggish growth in jobs and income of the eight Obama years.

A win will be a signal that on the big issue of the day, the House, Senate, and president can and did work together to defeat the Washington special interests to create tax reform and tax reduction. Republicans had hoped to face Americans with two wins: an end to Obamacare and tax reform. Now Republicans succeed or fail with the power of one big win: tax reform.
