Quite the contrary, the base proved potent in influencing congressmen NOT to vote for a bad bill being proposed by Paul Ryan.
I understand the impulse of Trump supporters to blame Ryan for the repeal and replace failure, but fair-minded, objective observers correctly note that Trump was fully engaged in the attempt to pass it. Trump himself is on record saying he supported that bill "1,000 percent). Ryan voiced high praise for Trump's personal involvement in getting the bill passed.
If "... the base proved potent in influencing congressmen NOT to vote for a bad bill ..." they did so in direct opposition to Trump, and thereby saddled him with one of the biggest failures of his administration. If Trump himself chose to support a "bad bill," which he clearly did, it indicates poor political judgement and ignorance about how the legislative process works.
While it can be said of any failed or stalled legislative initiative, or of any new president, that it or he is a work in progress, the same can be said for the developing impeachment scenario I foresee. In all three cases, speculation about a future outcome is involved; and all such speculation is based on the speculator's perceptions, interpretations, emotions and thoughts.
Work in progress suggests something will be different in the future. To date, I see little evidence of change in the man Donald Trump. He continues to make vague pronouncements that inspire hope in his uncritical base. He continues to manifest the narcissistic personality he brought with him to office. He does not appear to be learning from his mistakes. As the budget battle approaches, his approach to Congress is the same as it was with repeal and replace.
There is a big difference between the Oval Office and Trump's corporate board room. If Trump does not change, he enjoy the occasional win while falling flat on his face again and again.
