Can Trump save the Republican party?

Donald Trump's offer to take over the job of Speaker of the House of Representatives for 90 days following the ousting of Kevin McCarthy says more about American politics than almost anything else. He sees himself as the saviour of the country but also the saviour of the Republican Party. Presumably he would have fitted being Speaker in between campaigning to be president and appearing in countless trial hearings on the four indictments he is facing. The fact that some Republicans took this possibility seriously shows what state the party is in right now. It's leaderless and clueless. Trump's offer didn't last long because he then gave his backing to Ohio Congressman Jim Jordan, a stalwart Trump supporter, to take the Speaker job. You can't get away from Trump, he is everywhere, getting involved in everything, and it's clear the Republican party can't survive without him, or they think they can't survive without him. No other politician in the Republican party has his sort of clout and backing. Never mind that a judge has called him a fraud, that it's alleged he gave away secrets about American nuclear submarines to an Australian billionaire friend, that he allegedly tried to overthrow the election verdict in 2020, that he hoarded classified documents at his residence in Florida etc etc.
