Donald Trump in late push for support in Wisconsin

Donald Trump tried to put a difficult week behind him ahead of the Republican presidential contest today in Wisconsin.

The Republican front-runner is at risk of losing the Midwestern state to Texas senator Ted Cruz, an outcome that would dent the New York billionaire’s aura of inevitability and make it harder for him to win the 1,237 delegates needed for the party’s nomination for the November 8 election.

On the Democratic side, Vermont senator Bernie Sanders is trying to protect his lead over front-runner Hillary Clinton in opinion polls in Wisconsin and eke out another victory over the former secretary of state.
