We are in the midst of it - a huge shift towards Obama that cannot be stopped no matter what McCain/Palin do.
The McCain campaign is in chaos. They're sending Palin to the reddest of repuke strongholds to play defense - she's trying to stop the bleeding - trying to keep voters from defecting to Obama by resorting to fear and hysteria.
McCain faces a debate/townhall meeting tonight that, unless Obama makes a gigantic gaffe and falls on his face, will do absolutely nothing to change the race. He cannot win through tonight's performance.
Palin and McCain's have both been stating over the past few days that people don't know Obama. That it's THEIR job to tell people who he really is.
There-in lies their biggest miscalculation.
They don't understand that the American people DO know Obama. The American people have gotten to know him over the past 18 months. Obama has proven through his actions that he is the real deal - he does what he says. He has not changed his message one iota since the beginning. He has remained even-tempered and visionary regardless of the tactics of his opponents.
That is how trust is built and that's why we're seeing the shift in the polls now.
People trust Obama and there's nothing McCain/Palin can do to change that.
