Campaigning for the US presidential elections is gaining momentum. Candidates are seen addressing the voters. Allegations, counter allegations, acquisitions against each another is normal during elections. On Wednesday, at the Democratic convention at Philadelphia US President Barack Obama had asked people to vote for Hillary Clinton as his successor and defeat Republican candidate Donald Trump. Obama requested people to make ‘the obvious choice’ in the upcoming elections. When the crowd booed at the mention of Trump’s name, the US President said, “Don’t boo. Vote.” Obama criticised Donald Trump for not having a firm road map and only using scare tactics, he urged voters to shun the billionaire candidate. Obama said Trump is not a ‘plans’ gut neither aware of facts.
