Timothy Egan, in an essay in today's The New York Times, writes this:
"...facing a likely
trouncing in November, Trump has signaled that he will try to bring down
our democracy with him. His overlooked comment — “I’m afraid the
election is going to be rigged” — is the opening move in a scheme to
delegitimize the outcome.
"Because Trump is consistently barbaric
and such a prolific liar, it’s hard to sustain outrage over any one of
his serial scandals. But his pre-emptive attack on the electoral process
is very troubling."

And Washington Post columnist Ruth Marcus wrote, on August 3rd:
"Of all the dangerous things Donald Trump
has said, perhaps the most concerning is his assertion that the
election might be rigged. This irresponsible, unsupported suggestion
augurs poorly for Trump’s behavior in the increasingly likely event of
his loss."
