After the damage is done. That's akin to closing the barn door after the horses have scattered.
If the exit poll leaks are going to be addressed at all, then they need to be addressed in real time, as the leaks are being disseminated.
You ignore your enemy's moves at your own peril. Julius Ceasar saw the dust from Pompey's horses and was able to discern his army's movements and mount a counter offensive. If he'd just buried his head in the sand, he would have been soundly defeated.
We need to know where the dust is being kicked up and we need to mount a couter offensive. The enemy's armies are on the march. Should we just sit here until the battle is over?
No one is suggesting that we 'ignore' what the enemy is doing.
And with that, I sense that this conversation should be over.
I'm going to DO something about this election day. I'm going to PRAY.
FAR more effective than chatting about what the exit polls say.......
