It seems clear that the Republican Party is in the throes of dying as a major political party, as so many Republicans, both office holders and ordinary voters, cannot imagine either Donald Trump or Texas Senator Ted Cruz as their party’s nominee.
Only Ohio Governor John Kasich is left from the mainstream element of the party, but he cannot win the nomination on the first ballot, and has to hope for a contested convention, which does seem more likely as time passes.
Kasich has the best chance, in public opinion polls, to defeat either Hillary Clinton or Vermont Senator Bernie Sanders, while both Trump and Cruz lose in competition against both Democrats.
And there is the issue how Republicans would work with either Trump or Cruz as President, as most Congressional Republicans are turned off by both of them.
We could, in theory, have a Republican Party, or a shell of a party, in warfare against their own President, an event which would be unique in American history!
