I think from what John McCain knew about Governor Palin he did a good job vetting, as you Americans like to call it, however I don't think he did enough research prior to selecting Governor Palin as his running mate. I doubt the McCain campaign, nor hardly anyone expected a large barrage of dirt to come and tarnish Governor Palin.
tropper gate was already known.
the only punches that have been landed on Palin are from Bristol's pregnancy, which McCain claims he knew. And judging from the fact they're flying in the boyfriend, it looks like they had it planned to dump the news on Labor Day and bring the boy front and center Wednesday.
Was it a crazy plan? Absolutely. Would I have chosen Palin knowing that Bristol was pregnant? I highly doubt it.
IF nothing else damaging is found, then the vetting process was right on the mark.
Does that mean she was a risk worth taking considering all the known baggage? That remains to be seen.
