The Republican candidate's popularity has been driven by his unusual campaign declarations
A number of messages aimed at Donald Trump were seen in the skies above California on New Year's Day, ahead of the big Rose Bowl football game.
The messages were written in the sky above the famous Rose Parade, which takes place every New Year's Day in Pasadena ahead of the game.
With Iowa fans in town to support the Hawkeyes and the caucuses scheduled in that state for the beginning of February this year, the messages were perhaps hoping to get a few would-be Trump voters to reconsider their decision.
The messages, many of which were too long to capture in one photo, declared that "Trump is disgusting", or claimed he was a fascist, and lampooned his campaign his slogan by stating that "America is great".
The messages also included a link to a website AnybodyButTrump.us, which contains a number of quotes and videos from Trump throughout his campaign which have seen him hit the headlines for the wrong reasons.
The site uses similar language to that which was used in the messages written in the sky, declaring Trump to be disgusting, and claims to be run by a group called We The People.
Trump hasn't taken to Twitter to respond yet, as he's been mainly aiming a few digs at fellow candidate for the Republican nomination Jeb Bush.
.@JebBush is a sad case. A total embarrassment to both himself and his family, he just announced he will continue to spend on Trump hit ads!— Donald J. Trump (@realDonaldTrump) January 2, 2016
