Mr Trump has now won states in the east, south, and west of America, showing he has nationwide appeal. Polls show him ahead in most Super Tuesday states, while his odds are at a record high on global betting websites - in some cases at 1/2 for him to win the Republican candidacy.Yesterday, in a sign of Mr Trump's growing hold on the race, Chris Collins, a Republican congressman from the mogul's home state of New York, became the first member of Congress to endorse him, saying in a statement "it's time to say no to professional politicians and yes to someone who has created jobs and grown a business."
