I don't think they can get rid of the constitution. It would require a near total control of all judges right now and I don't think they have that.

What they will instead do is continually test the boundaries and shift them. They will also put in loyalists. Aka corruption. This already happened in the army by the way. It's fascinating to see how a democracy is turned into a dictatorship.

Happened before, for example in Germany. Not sure "fascinating" is the word I'd choose.
