Once again, Donald Trump's off-the-cuff style of speaking during his rallies has set the presidential campaign ablaze.

The Republican nominee said that gun-rights advocates could "do something about" Mrs Clinton after she gets elected and tries to appoint judges. What could that be? His campaign's explanation that they would organise and vote simply doesn't track.

In a political environment where Trump supporters chant "lock her up", say Mrs Clinton should face a firing squad or worse, the Republican candidate's open-to-interpretation remarks likely throw gasoline onto a smouldering fire.

Americans often complain about the programmed nature of their politicians. Trump's faithful, in particular, deride polished candidates with their considered answers.

There's a reason why those seeking the presidency are exceedingly cautious about what they say. Every word is closely parsed, both in the US and around the world. A verbal misstep can be devastating.

Mr Trump ignores these rules. And as his poll numbers sink, he and his campaign are taking on a bunker mentality. The media are biased, the elections could be rigged, the polls are skewed, and Mrs Clinton is an unstable menace. It's Trump v the world.

Twitter users were quick to respond to Mr Trump's comments, criticising the Republican nominee for appearing to encourage gun violence.

Connecticut Senator Chris Murphy said that "unstable people" who hate Mrs Clinton could respond.
