You’re reaching there. Typical politics would give him the money from congress after winning election.
It’s ‘magical thinking’ IMO that congress would shut down the government- and he could/would put them in that position- to stop him.
The problem is Congress has to send him the legislation that does what he wants. Otherwise there's very limited stuff he can do by EO.
As much as we complain Obama's executive amnesty is still being blocked by the courts. Trump won't fare any better.
Obama had the entire Democratic party fully behind him. Don't forget, whatever happens with Trump the congressional situation won't be radically different after the election and he's going out of his way to alienate the establishment types that will still control the Republican caucus. Again, I'm not sure he's cut out for this whole co-equal thing.
