If Donald Trump wants to beat Hillary Clinton, he needs to win these 5 states

The Republican nomination is in his grasp. Now the question becomes: Can Donald Trump win the White House?

With a decisive victory in the Indiana primary Tuesday, the billionaire businessman who was initially ridiculed as a fringe candidate was declared the party's presumptive nominee by Republican National Chairman Committee Reince Priebus. Trump has defeated 16 primary rivals, including some of the GOP's top governors and senators, and defied the conventional wisdom that he wouldn't run and couldn't win.

His primary rivals and other senior Republicans have argued that Trump's lack of governmental experience and his unprecedented negative ratings — including among such crucial electoral groups as women, Latinos and young people — would doom his prospects in November. But as Trump likes to remind people, the conventional wisdom has been wrong about him from the start.
