So the party that controls both houses of Congress, the majority of governorships, and the majority of state legislatures should just dissolve because we haven't won a Presidential election in a while?
Yes because a loss on a national level affects those elections. We will undeniably lose the Senate majority and seats in the House if we nominate Trump.
It is most definitely deniable that we will lose the Senate if Trump is the nominee. Sure we'll lose a few seats, but there's no guarantee that the Democrats will gain a majority. I can guarantee, however, that the Republican Party will not dissolve, no matter if Trump gets nominated or how bad we lose. I'm not sure how educated you are in US history, but if the Republican Party was going to dissolve it would have happened during the FDR years. The Republicans oversaw the Great Depression and took massive losses in the House, Senate, and well, pretty much everywhere. The Democrats had a lock on the White House for over 4 terms and had built a solid coalition that looked unbeatable. The nation had dramatically shifted to the left, and the role of government would forever be changed. Still, the Republican Party did not dissolve. The Party is much stronger than you think, and it will take a little bit more than Donald Trump to cause the death of this Grand Old Party.
