President Joe Biden of the United States has reinstated his commitment to build on the America dreams as world's power as he launches re-election campaign.

U.S Republican party presidential candidate Hillary Clinton is tied with Donald Trump in new polls among likely voters released on Thursday night by CBS News/New York Times poll after a turbulent week battling health issues.

As he seeks to make inroads with African-Americans and other minority voters, Donald Trump dramatically escalated his rhetoric against rival Hillary Clinton, accusing her of being a “bigot” who does not truly care about blacks and Hispanics.
