Des Moines Register:

Editorial: Trump should pull the plug on his bloviating side show

It's time for Donald Trump to drop out of the race for president of the
United States.

People who run for public office typically perform a great public
service, regardless of whether they win on Election Day. That's
particularly true of presidential candidates, most of whom must devote
two years of their lives to hard-fought campaigns that involve
staggering personal and financial sacrifices, all in an effort to serve
their country.

And then there's Trump.

In the five weeks since he announced his campaign to seek the GOP
nomination for president, Trump has been more focused on promoting
himself, and his brand, than in addressing the problems facing the
nation. If he were merely a self-absorbed, B-list celebrity, his
unchecked ego could be tolerated as a source of mild amusement. But he
now wants to become president, which means that he aspires to be the
leader of the free world and the keeper of our nuclear launch codes.

That is problematic, because Trump, by every indication, seems wholly
unqualified to sit in the White House. If he had not already
disqualified himself through his attempts to demonize immigrants as
rapists and drug dealers, he certainly did so by questioning the war
record of John McCain, the Republican senator from Arizona.

Not fair. The list of GOP 2016 presidential wannabes is packed with
bloviating assholes like Ted Cruz, Rand Paul, Bobby Jindal, et cetera.
Why single out The Donald?
