Aug. 24, 2015 — Quinnipiac University simultaneously polled the swing states of Florida (1,093 registered voters), Ohio (1,096 registered voters), and Pennsylvania (1,085 registered voters) during the Aug. 7-18 period and found that neither Donald Trump nor Jeb Bush is the strongest Republican against a trio of potential Democratic nominees. Rather, it is Florida Sen. Marco Rubio who scores the highest in ballot test pairings opposite his Democratic counterparts.
The young senator, however, isn’t quite as strong on the Republican primary ballot test, placing third in all three states including his own. The Q-Poll’s three state combination does show that Rubio would be the Democrats’ most formidable opponent, therefore suggesting he has the potential of likewise creating a surge among Republicans.
The pollsters paired three Democrats: Hillary Clinton, Vermont Sen. Bernie Sanders, and Vice President Joe Biden, with three Republicans: Trump, Bush, and the Florida senator. The data finds that Rubio is the only one of the trio who leads Clinton in each of the three places. In fact, he tops all three Democrats everywhere in the tested region with the exception of trailing VP Biden in Ohio, but by just one percentage point, 42-41 percent.
