Iceman90 Dave has previously advised "I simply post reliable poll results, usually without comment so no crowing."
Under Dave's thread header latest reputable poll Dave wrote:
"Morgans is the poll I rely on as they have an excellent track record on politics"
The above type of statements are known as a loaded question (also known as a complex question or trick question)
They are a form of misleading discourse where something is implied without being said explicitly I.E. I simply post reliable post results combined with Morgans is the poll I rely on implies that all other poll are not reliable and as such Dave does not post them without actually saying so.
For Dave to argue endlessly that he has not said other polls are unreliable is word play at best. Another example of a complex question might be Dave have you told the truth today.
