Often internal polls show completely opposite things, at least I recall them doing so in the past. IE......2004 kerry’s polls had him winning. Bush’s had him winning.
internal polls just show what the candidate wants to hear to a degree.
However, I do think like in 2004, the republican polls will be closer to reality this year, so we can win this.
wrong... internal polling didn't show Kerry winning... exit polling on election day showed him winning... that's because the exit pollers were mainly asking women voters... not a good poll... but this had nothing to do with internal polling... in fact, during all the campaigning, Kerry is known to have said, "I can't believe I'm losing to this idiot."
You make an excellent point. But let’s consider this: Soem polls are just “We talked to these people and they said this” but others are run through a turnout model. If one campaign’s turnout model is more realistic than the other (and I think that ours must be because Obama has to be counting on massive youth vote and getting around 90% of the Dem voters) then only one would even be in the ballpark.
