Donald Trump is a double agent for the Clintons. He's only running for president to lose to Hillary and shoehorn her into office so she gets painted as America's savior from the evil dictator that Trump is posing as. He's a plant made to steal the Republican vote by posing as a controversial anti-establishment candidate from other Republicans who actually have a chance at beating Hillary, ensuring her a straight shot to the White House.
But even if he isn't, he has NO chance at beating Hillary Clinton. Many news articles are already stating that Trump will be fighting an uphill battle against Hillary and isn't likely to win. Even if he were to run against Bernie Sanders, he still trails Bernie by a wide margin on national approval polls. Donald Trump has little to no chance at becoming president.
