That is no longer an option. With Trump, it probably never was. In a recent speech, he has repeated his threat of violent riots from his MAGA supporters if he is prosecuted or detained. January 6th proves that these are not empty words. What part of his overt threats are you deaf to?
Merely preventing him from running for office is not enough. He has to be prosecuted, found guilty, and sent to prison for attempting to overthrow the US government. Failing to prosecute him, will leave him free to plan a more violent attempt to overthrow the government. The same goes for any of his violent supporters.
Only after Trump is imprisoned will others in the GOP no longer feel that they have to kow-tow to the pro-Trump GOP primary voters. Until then, the GOP, as the party that supports violent overthrow of the US government, is politically dead-in-the-water.
