One thing to remember, however, is that whoever pays for a poll has the right to keep the results private if they choose to do so. The sponsor of such a privately-funded poll will use it how they see fit... and if it helps their cause to release it prior to an election, they will do so...
However, they obviously did not choose to do so in this case... but maybe the polling company has the right after the election to comment on it/release the results, because doing so doesn't affect the paying client.
If any of us pays for a poll, we get to decide how it gets used, or not used...
Just sayin' ...
That's certainly the case...I did find it surprising that the polling firm admitted that they didn't release the poll results because they found them implausible. It won't help their reputation, given that people will wonder in the future what other results they're hiding.
