"Vice President Joseph Biden, who is spending his time in seclusion, contemplating whether to take on Secretary Hillary Clinton in the Democratic primaries for president, has some new information to consider," said Peter A. Brown, the poll's assistant director.
"The first Republican debate mattered," said Peter A. Brown, assistant director of the Quinnipiac University Poll. "Gov. Jeb Bush got middling debate grades and slips in the GOP horse race. Yet he does very well when voters rate the leading Republican candidates on personal characteristics. He scores best on honesty, empathy and temperament to handle an international crisis, while finishing a close second to Trump on leadership. Wisconsin Gov. Scott Walker gets very low debate grades and all but disappears from the Republican primary list."
