Neither one currently holds an elected or appointed office. They have no lawful power...yet. Therefore, they shouldn't try to insert themselves into the process.
It blew up in their faces, as it turns out, but that's beside the point. A number of Republicans decided to break ranks and not demonstrate fawning fealty to Dear Leader. This could be an indication of more disunity within the Pig Party. I'm sure that they realize that Trump won't be around for long, and it might benefit them to distance themselves from him.
But all that aside--what do you think of two billionaires trying to strong-arm the government so that they won't have to pay taxes? Do you think this country wants to be led by the super-rich? Do you think that either Trump or Elon have ever shopped for groceries? Paid for a tank of gas? Worried about a high utility bill? Do you think that either one of them even understands what cutting Social Security/Medicare, instituting massive inflation, and running up a YUGE budget deficit will do to the average Joe?
And...do you think they give a shit?
