He speaks some truth. You can virtually guarantee if Republicans take the House in 2022 Biden and/or Harris and/or both will be impeached (but not removed). This will become true virtually anytime the House is controlled by an opposite party since every President since Nixon has f'ed up something along the way and been involved in scandal....there's not one that's made it through 4 years Scott Free (hah!). The R voters will be looking for revenge and won't tolerate gentlemen like Jeb! who don't know how to fight.
Even if you don't buy that the election was stolen, there's plenty in the R perception that it wasn't "fair": biased media, biased pollsters, tech company censorship, suppression of the Hunter story, mass mail in voting (sometimes without signature verification, done hastily citing COVID), the Russian conspiracy, the first impeachment, Nancy withholding aid for political purposes, the lockdowns. Then there's the D overreach: the 2nd impeachment, Twitter censorship, calls for reconcilation committees, the villification of Trump voters, moves to ban books. The R's won't be looking for a unifier...they will be looking for someone to burn it down (Pence ain't it). The Rs will be looking for an Anthony to replace Caesar.
