That had such a huge effect on the PA primary after all. Considering that Hillary won by what you claimed earlier was the absolutely minimum she could win PA by (someone made a comment about how she might get a win by 9 points and you replied "She's winning PA by at least 9.")
Man that post just me feel good reminding me of how we deleted that stupid whore and your beloved goddess who you claimed I was going to have to support with such certainty. Ah, awesome!
That's kind of a dickish thing to say.
