Another factor as I recall is the previous governor (piss be upon him) put very little effort into getting re-elected after putting even less effort into taking charge when he sat in the big chair.
Like all he wanted to do was punch a political ticket.
Corbett definitely did not do the PR game well at all, and the teachers unions were galvanized against him.. for the children and all.
Of course this new guy still hasn’t put forth a realistic budget so schools still haven’t gotten their books this year, so so much for the children.
