Regarding China and "Democrats tiptoeing", it's obviously got nothing to do with Democrat or Republican, every administration for 37 years has had the same policy and acted the same way. It's not Democrats vs Republican (I thought this kind of classification by label was a bad thing??) it's Trump vs. everyone else.
Carrier deal is good optics for those not really paying attention, but it's nothing like what he promised during the campaign (the opposite, it's exactly what he railed against actually). What he actually promised during his campaign and even re-promised after the Carrier deal was consequences, but that's pretty hollow given Carrier is still shipping more jobs than the Carrier deal saves despite the threat of consequences.
On cancelling Obamacare, well we do have an idea with what they want to replace it with;
save and pay for health care yourself. That the US is pretty much the only first world country without some kind of basic universal health care should almost be a human rights issue, and Republicans' desired changes for health care haven't ever been towards that.
