Trump’s Conquest of the Republican Party Matters to Every American

With Donald Trump’s victories on Tuesday, he has moved to the cusp of securing the 1,215 delegates necessary to win the Republican Party’s presidential nomination. The rest is a formality. The party has become a vessel for the fulfillment of Mr. Trump’s ambitions, and he will almost certainly be its standard-bearer for a third time.

This is a tragedy for the Republican Party and for the country it purports to serve.

In a healthy democracy, political parties are organizations devoted to electing politicians who share a set of values and policy goals. They operate part of the machinery of politics, working with elected officials and civil servants to make elections happen. Members air their differences within the party to strengthen and sharpen its positions. In America’s two-party democracy, Republicans and Democrats have regularly traded places in the White House and shared power in Congress in a system that has been stable for more than a century.
