If he wants to make a difference, let him run for Governor of California as a Republican next year and enact a Conservative agenda (you know, everything that Ah-nold Schwollenpecker claimed he was going to do before he ended up governing like every other Communist Democrat hack). He does that, maybe we can see about him becoming President in 2024.
If he really wants to make a difference, let him donate his pocket change ( which, for us, would be several millions of dollars) to the Trump Re-election Campaign and become a well publicized cheerleader for the POTUS' current work and policies.
We don't need another Ross Perot to throw the election to the RAT party.
