DES MOINES, Iowa (AP) - Republican Donald Trump and Democrat Bernie Sanders hope to ride voter energy into victories in Monday's Iowa caucuses, as Ted Cruz and Hillary Clinton bank on sophisticated get-out-the vote operations that have been months in the making.
The caucuses kick off voting in the 2016 presidential nominating contests, marking a new phase in a tumultuous election that has exposed Americans' deep frustration with Washington and given rise to outsider candidates.
The race for supremacy in Iowa is close in both parties. Among Republicans, Trump appears to hold a slim edge over Cruz, the fiery senator from Texas. Clinton and Sanders are locked in an unexpectedly tight Democratic race, reviving memories of the former secretary of state's disappointing showing in Iowa eight years ago.
