I know he has been talking about a third term for over a year now, so it is something he's considered. The constitution is little more than a historical document at this point, so there is a possibility he might try it. He tried an insurrection after all. However, I don't see it happening for a couple of other reasons, the primary one is that Thiel wants his man Vance at the helm. Another one is that he is falling apart mentally and phyisically so Father Time will probably take care of that.
But either way, he definitely needs to consider his popularity, as a half-decent showing in the midterms is his only route to avoid accountability. If the GOP absolutely tanks in the midterms, the Dem Congress will impeach him repeatedly. If it gets really bad then they might even get enough Senate seats to convict him. You know he is worried as they are pushing this 'Save' act thing which is just another attempt to rig the vote.
