The Quinnipiac poll was for Florida and Pennsylvania (The Pennsylvania poll was Biden 52-44). For the enthusiasm question, President Trump has the lead:
2b. (If vote Biden q2) What is the main reason behind your vote for Joe Biden over Donald Trump in November: mainly because you like Joe Biden, mainly because Joe Biden is the party's nominee, or mainly because you oppose Donald Trump?
2c. (If vote Trump q2) What is the main reason behind your vote for Donald Trump over Joe Biden in November: mainly because you like Donald Trump, mainly because Donald Trump is the party's nominee, or mainly because you oppose Joe Biden?
Trump voters are voting for him; Biden voters are voting against Trump.
Quinnipiac doesn't release party breakdowns, but their national poll had a question that can be used as a proxy, assuming only the "die-hard" party members watched the entire conventions.
12. How much, if any, of the - Democratic/Republican National Convention did you watch or listen to: all or most of it, some of it, just a little, or none of it?
Given how popular the RNC convention was, having Democrats outwatching their convention versus Republicans watching theirs, I can only conclude that the Quinnipiac poll oversampled Democrats by at least D+7.

Thank you for your analysis.
Excellent. I wondered about that and didn't 'get it' until you explained why that had happened. Do you have a ping list? I'd like to be on it if you do.
