Why associate the comment you replied to with Trump, and why is associating that comment to Trump enough to dismiss criticism of publishing continuous polls as "far-fetched conspiracy theories"?

There have certainly been massive polling failures (and obvious push polling) in elections over the past decade that can be discussed rather than being dismissed for the sake of partisanship. The organizations who actually do the polling discuss these issues constantly without accusing each other of being deluded.
