Other presidents have campaigned on trade, before going back on their word. President Trump showed that he is committed to dumping TPP by signing an executive order to that effect.
The freeze on hiring Federal workers is an important weapon in the power struggle with Dems trying to keep Trump appointees at bay for as long as possible.
And the ban on foreign abortion funding shows Trump hasn't forgotten social conservatives either.
President Trump has shown the white working class voters who backed him that he means what he says about trade policy. If anyone hoped to keep TPP alive, that hope is now dead. He's also showing that he will reverse Obama's policy of starving the military while growing the bureaucracy. This is good news for anyone concerned about national security.
What is interesting about these executive orders is how they offer things to three different segments of the GOP base. The limited government people get a hiring freeze. The "Made in America" voter gets to watch a kick being administered to TPP. And social conservatives see a crackdown on foreign abortion funding. It's a statement that while the administration is still finding its feet, it intends to deliver on its promises to a range of Trump voters.
Add on mentions of the Jerusalem embassy move and the wall, and it's quite a bonanza for different flavors of conservatives.
