Donald Trump looked poised to strengthen his lead in the Republican presidential race when 11 states vote on Tuesday, an outcome likely to intensify concerns among party leaders who consider him a usurper, Reuters reported. In the Democratic race, former Secretary of State Hillary Clinton would go a long way toward cementing her path to the nomination if she scores big victories of her own over democratic socialist Bernie Sanders on Super Tuesday. Opinion polls showed Trump leading in nearly all the states that will hold primary contests or caucuses, many of them in the South. The exception appeared to be Texas, the home state of U.S. Senator Ted Cruz, who enjoyed a narrow lead and was in desperate need of a victory. Super Tuesday is the biggest single day of state-by-state contests to select party nominees for the Nov. 8 election to succeed Democratic President Barack Obama. Voting stretches from eastern states to Texas and Minnesota, with the first polls closing at 7 p.m. EST (midnight GMT) in Vermont, Virginia and Georgia and first results expected soon after.
