That's my impression as well. The problem being that there's at least ten RINOs in the legislature for every one Conservative -- or honest Republican, for that matter. There is no functioning legislative infrastructure anymore that he can depend upon as president of his party for backup. As for the FBI and the DOJ, they blatantly work for the Dem Party at this point in time. How much power does an 'out of favor' president actually have? We shall see.
Of course his other problem is that almost all of his aides and whatnot were actually RINOs willing to sell out to the Dem Party in a heartbeat and sell out Trump in the process.
