DES MOINES, Iowa (AP) — Only a week remains before the Iowa caucuses — the first contest in a tumultuous presidential campaign that has challenged long-held political assumptions.
The Republican race in Iowa is Donald Trump's or Texas Senator Ted Cruz's to lose on the night of February 1st.
Some party leaders are coming to grips with the prospect of Trump as the nominee. But there's a group of more mainstream candidates battling to beat expectations in Iowa, and then head into the New Hampshire primary on Feb. 9 with momentum to challenge the front-running billionaire.
The Democratic race has evolved into a surprisingly heated contest between Hillary Clinton and Senator Bernie Sanders.
Sanders — the Vermont senator who's a self-described democratic socialist — has energized young voters and liberals.
