I duno. Maybe they made the calculus that shutting down the government would boomerang on us.

Millions will die. The ACA took 50 years to arrive and it was damned difficult. Folks died (how dare they) and switched parties. I don’t think we will get healthcare back. Medicare is next. We need new leaders

He may drop a few more if the bottom were to fall out of the economy, but 36 is pretty awful.

That's likely his floor unless they become convinced he's a feckless autocrat.

to blame others (i.e. Democrats)!!

I think his absolute floor is 30%. 25% are true believers for one reason or another & 5% that don't care about anything but lower taxes.
It could be 36%, as you say, but I seriously doubt it's under 30.

Or it's amazing that 30% ruin the entire country.

Take your pick.

If prices keep skyrocketing he's going to lose some percentage of even this sub-basement.

At this point, I think his only plan is to take as much as he can, hold on to it as tightly as he can, and keep as much as of it as he can after all is over and done. His support among GOP leadership is flaccid and getting softer every day, last week poured dye on the the stain and showed obvious cracks and fault lines.

The less amount of time a president has in his lame duck term, the less influence they're usually able to exert over their party, because congresspeople know they just have to wait out the president until his term is over.

Especially if the midterms are ugly, both house and senate republicans will start putting distance between themselves and him.

But, there's room for improvement.

36% still support Trump
I agree

The referenced polls wander from the mid 30s to low 40s without any real trend.
