Now my thoughts coincide with Ezra Klein who writes well here and here.
However I want to examine two policies of Trump when at his 'best' in the first 30 minutes of the debate.
First he said Mexico's VAT was a tax on US imports. Err it also taxes Mexican goods at the same rate.
Second he wants to renegotiate every bilateral agreement because the US lost out.
How many nations do you think would renegotiate an agreement which would involve the US having a trade surplus with each country. Yep. none. Thus trade barriers would rise.
Only Katesy could think they are good policies.
