I don’t doubt the man’s intelligence or competence. That’s why he is so scary.
What I do not like about him are his policies. If he were a complete dolt, I wouldn’t worry about his ability to manipulate and/or negotiate in order to implement his political ideals. While he probably hasn’t sad down and read the bill word for word, I’m sure he has been briefed on the details of the bill, specifically any vulnerabilities it may have. I admittedly have not read the bill, but have heard from those whom have that it was well written and done so with the expectation that it would be challenged. This being the case, he is appealing to the inaccurate and emotionally fear based rhetoric that has been offered as opposition to the bill as apposed to challenging any legitimate weakness.
