Tx,
This is what I was saying about not having any hard numbers now that the election’s over. The site you linked was his old pre-election campaign page —note how the news updates stop at election day. The link I posted was his post-election dot-gov page where he turns promises into policy. For example you can see how one change is he’s no longer wanting to leave NAFTA.
Maybe in a few days he’ll update the new site to include numbers, altho my guess is he’s now thinking how to get his ideas past congress so the numbers will be subject to revision for some time to come.
