Will Trump become an Albatross for the GOP?

There's clearly a base in the GOP that loves Trump however in the same vain there's a sufficient population that will vote for anyone that is not Trump. Do you think that if Trump loses the election in November he will keep on trying to get elected until he either wins his second term or eventually passes away? Will Trump staying around hurt the GOP or help it? On the flip side of that what will become of the GOP if he wins a second term, leaves politics or passes away? It seems like he's the only one who can do MAGA properly.
