Can the Republican Party be saved?

Party split is inevitable, and horrible. The two sides of the Republican Party are as different as the Dems and Republicans from 30 years ago. The party of Pence, Ryan, McConnell does not fit with the MAGA movement at all. One side is viewed as reckless, brash, and strong and the other as polished, ineffective and feckless. The most difficult part to watch is the split is EXACTLY what the left wants. I feel we will remain under Dem control for at least another 10 years. Is there a realistic way out of this? A third party will not work. Shaming the MAGA crowd will not work. Ignoring the fact that such a large group exists will not work. Trump republicans will never be free from media scorn. The Romney republicans will only wear mom jeans and walk in pride parades.
Is this the end of my the Republican Party in name or viability?
