Before going for his vacation in Hawaii, President Obama joked that the "most important" thing happening at the White House was him watching the new Star Wars movie.
Trump was quick to notice that and he quickly attacked the President:
"We're in a serious war [and] our president is busy with another war," a new video ad said on Trump's Instagram account.
"We need a real president. Time for a leader with real priorities," Trump's ad said.
At the same time, 28 percent of Republicans said they "would definitely not support Trump," while 61 percent of general voters said the billionaire does not share their values.
Two leading Democratic candidates, former Secretary of State Hillary Clinton and Senator Bernie Sanders, beat Trump in potential matchups, according to the poll.
Moreover, 59 percent of the polled voters said Clinton has a good chance of defeating a Republican presidential contender during the 2016 election.
