Unfettered

Former Republican candidate John McCain became the latest senior Republican to criticise Mr Trump for his attack on the parents of US Army Capt Humayun Khan, who was killed by a car bomb in 2004 in Iraq, at the age of 27.

Senator McCain, a veteran of the Vietnam War, said in a strongly worded statement that Mr Trump did not have "unfettered licence to defame the best among us".
US election: Donald Trump says Hillary Clinton is 'the devil'

As a matter of fact, Senator McCain yes, he does. As long as he doesn't stand to lose any support for his comments, he's going to keep making them. Donald Trump appears to have learned something that would be handy for the rest of us - not to judge himself or his actions by the standards of his critics. People may think that Mr. Trump should be doing more to appeal to people who don't already support him, but that's not normally the way politics works, or we wouldn't have so many negative campaigns.

The secret to winning elections is typically keep the people who back you enthusiastic and set out to get the people who don't like you to doubt the other options enough that they stay home on Election Day. And as long as Mr. Trump can keep his supporters clamoring for more, he's not the least bit worried about what everyone else thinks.
