Donald Trump has the highest unfavorable rating since Gallup began tracking the indicator for nominated candidates from either political party during the 1992 elections. Just two days before the Iowa caucuses, 60 percent of Americans surveyed view Trump unfavorably, versus 33 percent who see him favorably.
By comparison, Democrat Hillary Clinton's rating is 52 percent, while Jeb Bush's is 45 percent.
Chris Christie's is at 38 percent, while Ted Cruz's is 37 percent, Marco Rubio 33 percent, fellow Democrat Bernie Sanders holds 31 percent, while and Ben Carson's rating is 30 percent.
"The bottom line is that Trump now has a higher unfavorable rating than any candidate at any time during all of these previous election cycles," said Frank Newport, Gallup's editor-in-chief.
