Donald Trump was right. Countless others were wrong.

The pundits and pollsters who said the former reality TV star could not win the U.S. presidency, the Republicans who shunned him, the business leaders who denounced him and the Democrats who dismissed him failed to fully understand the depth of his support.

In a stunning victory over Democrat Hillary Clinton, Trump stuck to a plan that worked to perfection in the Republican primary, a campaign built around his blunt-talking celebrity persona, his command of social media and his anti-establishment message of change.
