3/13/16, "Trump Still Leads NC; Bond Likely To Pass," Public Policy Polling
"Way back on July 8th PPP released a North Carolina poll that was
the first survey to find Donald Trump leading the Republican race
anywhere in the country. 8 months later our final poll of the GOP race
finds Trump primed to book end that first poll with a victory in the Tar
Heel State. Trump is polling at 44% to 33% for Ted Cruz, 11% for John
Kasich, and 7% for Marco Rubio.
Compared to a month ago Trump's support is up 15 points and Cruz's is
up 14 points. Kasich's remained in place, and Rubio has seen his
support collapse 9 points. Trump appears to already be building up a
lead among early voters- he's at 46% to 38% for Cruz, 11% for Kasich,
and 4% for Rubio. Among those planning to vote on election day Trump
gets 43% to 32% for Cruz, 11% for Kasich, and 8% for Rubio....
One big thing Trump has going for him is that he has the most
committed supporters. 89% of Trump voters say they'll definitely cast
their ballots for him, compared to 84% of Cruz, 68% of Rubio, and 65% of
Kasich supporters who say the same for their candidate....
Continuing the recent trend Rubio is now
under water in his image with North Carolina Republicans as just 39%
see him favorably to 48% who have a negative opinion....Full Results Here."
