Former US President Barack Obama said that November midterm elections would give Americans “a chance to restore some sanity in our politics." He took another swipe at his successor, Donald Trump as he raised his profile campaigning for fellow Democrats to regain control of the House.

During a 20-minute speech in the key Southern California battleground of Orange County, Obama did not mention the US President Donald Trump by name but the allusions were clear.

“We’re in a challenging moment because, when you look at the arc of American history, there’s always been a push and pull between those who want to go forward and those who want to look back, between those who want to divide and those are seeking to bring people together, between those who promote the politics of hope and those who exploit the politics of fear,” he said.
