The final Quinnipiac poll in Iowa finds Donald Trump jumping to a solid lead over Ted Cruz, 31% to 24%, followed by Marco Rubio at 17% and Ben Carson at 8%. No other candidate gets more than 4%.
In the Democratic race, Bernie Sanders holds a slight lead over Hillary Clinton, 49% to 46%.
Said pollster Peter Brown: “The size of the turnout tonight will likely be the key factor, especially on the Democratic side. High turnouts with lots of new caucus participants likely would mean a good night for Sen. Bernie Sanders, and for Donald Trump.”Save to Favorites
