the "Catholics" who dissent from the Church's teaching about the Real Presence (80% of weekly Mass-attending Catholics)

You've got this way off. The 80% statistic is actually about 66% according to the poll, and that's from everyone who identifies himself as Catholic. Sinkspur has also posted polls showing that many who answered incorrectly simply didn't understand the terminology used in the phone survey, but accept the real presence - Trent's exact definition isn't often used in catechesis anymore, and even Vatican II never used the term "transubstantiation".

I'll post the polls again, but the idea of conducting a phone poll with arcane theological definitions, all four of which resemble each other closely, is simply ridiculous.

In other polls, when the questions are clarified, 80% of Catholics actually believe that the bread and wine are the Body and Blood of Christ.
