Donald Trump doesn’t get to take part in the set-piece election TV debates yet, but he certainly can’t seem to keep away from them. Approaching Saturday’s Nevada Democratic caucuses, the Trump campaign have chosen the day of the Democrats debate to publish a full-page ad attacking the leading candidates in the Las Vegas Review-Journal, the city where it takes place.
The advert, which pictures Elizabeth Warren, Joe Biden and Bernie Sanders, declares that “Democrats will kill Nevada jobs” and promises that “Big government socialism will wreck the economy”. It goes on to extol Trump’s record in office.
