I do not see Musk wanting to be the speaker of the house and show up everyday but speaker Johnson is on his way out. The next speaker will probably be a Musk puppet.
A government shutdown is due tomorrow because Trump tweeted he wants a debt limit increase to occur in the Biden administration and not in the Trump presidency. That blew up the agreement that was made to continue the government through Christmas. Musk has more power than the speaker. Elon can't be President because he is an immigrant.
The TrumpMUSK Presidency is the next best thing for billionaires.
