Real estate mogul Trump has widened his lead to 20 points in a brand new Zogby Analytics poll taken after the second Republican presidential debate. The new poll of 405 likely Republican primary/caucus voters nationwide with a margin of sampling error of +/- 5.0 percentage points, conducted September 18-19, shows Mr. Trump with 33% (up 2 points from his pre-debate 31%). In second place is neurosurgeon Dr. Ben Carson who actually dropped 3 points to 13%. Former Hewlett Packard CEO Carly Fiorina, widely considered to be the big winner in the debate, moved up from just 2% last week to 7% and fourth place in the new poll - just 2 points behind former Florida Governor Jeb Bush's 9% (which is exactly where he was last week).
Texas Senator Ted Cruz moves up a point to 5%, followed by Florida Senator Marco Rubio, Kentucky Senator Rand Paul, and Ohio Governor John Kasich all tied at 4%. New Jersey Governor Chris Christie, who by many accounts, had a good debate night, stayed at 3%.
The biggest losers in the post-debate poll - besides Dr. Carson's drop - were Wisconsin Governor Scott Walker who fell from 5% to 2% and former Arkansas Governor Mike Huckabee who polled 2% (down from 4%).
Mr. Trump's lead is across the board, among most major sub-groups - 36% among men, 30% with women, 30% Republicans, 39% independents, 29% moderates, and 31% conservatives.
Dr. Carson's best showings were among Republicans 14%, and conservatives 16%. Mrs. Fiorina did better among men (9%) than women (5%) and Republicans 8% than independents (5%). Mr. Bush scored 10% with women, 8% with men, 12% moderates, but just 6% among conservatives.
The poll was conducted in the middle of controversies regarding negative attitudes toward Muslims expressed by both Mr. Trump and Dr. Carson. Mrs. Fiorina gained the most traction from the debate but no one besides Mr. Trump has broken away from the pack.
