GEORGE WILL: Donald Trump has to perform now. The next thing he has to do is submit a budget. When the budget comes up calling for a trillion dollars in infrastructure spending, a tax cut that will lose by bipartisan assessment $5.8 trillion over a decade plus an increased military spending, plus protectionism, which means government deciding what Americans can consume at what prices and what quantities — what’s called economic planning and crony capitalism and all the rest – when that budget comes out, people are either going to rediscover their conservative convictions, or there’s going to be a banquet, a feast of people eating words they’ve spoken for 30 years…

[I] think when they realize all that you embrace when you embrace protectionism, enormous executive discretion, government planning essentially what we can consume and how the economy will work and who shall be winners and who shall be losers, when they realize the slippery slope they’re on, away from bedrock conservative principles, I think things will change by mid-summer.
