I don't think that it has anything to do with calls. I think this was planned to delay the filibuster to do the most damage to Republicans and Bush. My guess is they will use the calls as an excuse.
Again Frist is a fool. I could tell that Dinghy Harry was playing good cop, bad cop, all week.
Well it turns out that Salazars office is taking a poll now io the filibuster according to who calls him.
