The general rule in political propaganda is only to talk about polls that favor one's own candidate, isn't it? ;-)

(and such favorable polls can always be secured if one simply goes to the proper "source")

Bullshit. Bullshit. Bullshit. But it seems to work.

That's why I say there should be no polling allowed, period. It should be illegal to publish polling results in the media, because they in themselves artificially manipulate and alter the process...which is really just what they are intended to do by those who publish them.
