For the time being, at least, that Republican Party is dead. It was wounded by the tea party absolutists who insisted on political purity and rejected any compromise. Now it has been killed by Donald Trump.
Trump is an ignorant demagogue who traffics in racist and misogynistic slurs and crazy conspiracy theories. He champions protectionism and isolationism — the policies that brought us the Great Depression and World War II. He wants to undertake a police-state roundup of undocumented immigrants and to bar Muslims from coming to this country. He encourages his followers to assault protesters and threatens to sue or smear critics. He would abandon Japan and South Korea and break up the most successful alliance in history — NATO. But he has kind words for tyrants such as Vladimir Putin.
