Trump has won Indiana, so the Republican nomination is all but wrapped up now. A Democrat most of his life, he's successfully hijacked the Republican Party on popular issues such as trade,
boarder security, and American nationalism.
He's also won a lot of support for his attitude to politicial correctness. Say something that people get offended over? It actually doesn't matter.
Trump shows his liberal side by having a softer stance on abortion and guns, while his American isolationism is far more anti war than most of the Democrats.
Ted Cruz dropping out as the front running alternative for the Republicans, shows how deep the rot has been within the conservative establishment as he was also extremely anti-establishment.
With the worlds population exploding outside of the West, European, American, and Commonwealth boarders will either be closed, or flooded within a few generations. Trump has brought this issue to the most important election on the world stage.
Meanwhile, Bernie Sanders, the senile Utopian Socialist, has defeated Clinton in Indiana. While he'll never win the nomination thanks to the undemocratic values of the democratic party, he is showing how terrible Clinton has been. She can't even lock down her support base. If she can't convincingly beat him on policy, she'll see many supporters for Bernie either go to Trump (anti-establishment candidate) or simply stay at home.
So, if you're not taking Trump seriously, or writing off his support as just some backward hicks, it's time to Make America Great Again
