Yeah, if you ignore pollsters who engage in propaganda, not polling, that's what happens.
Sometimes what seems to be "propaganda" can turn out to be more accurate than what seems like "good polling." That's what happened in 2010 and 2014, IIRC. True, those were midterm years and this is a presidential year... but we have already seen plenty of major polling goofs in the primaries.
I agree that it is more likely that the other pollsters are right, but there is nonetheless a non-negligible chance that they are wrong and Fox/Rasmussen are right. To pretend otherwise is to dabble in dangerous delusion...
