Trump scored 20 percent in a new national poll of the GOP electorate, the highest tally received by a single candidate in Quinnipiac University's seven surveys over the last two years. However, 30 percent of Republican voters say there is "no way" they would vote for Trump, which is also the highest figure of any candidate.
Trailing Trump's 20 percent support is Wisconsin Gov. Scott Walker with 13 percent, and former Florida Gov. Jeb Bush, at 10 percent. Ben Carson, Mike Huckabee, Rand Paul, and Marco Rubio are all at 6 percent, putting them in a four-way tie for fourth place.
On the Democratic side, Hillary Clinton remains the frontrunner, with 55 percent, followed by Bernie Sanders at 17 percent. Joe Biden — who has not announced he is running — holds 13 percent. Despite her vast lead, Clinton also scored her worst-ever favorability rating, with 40 percent of voters viewing her favorably compared to 51 percent unfavorably.
