They have concocted another fictitious poll that has no basis in reality, held it for ten days, and released it at the perfect time in the news cycle to help their upstart liberal candidate. This poll has zero credibility and should be ignored out of hand."A Republican poll released last week showed McConnell with aneight percentage point lead over Grimes.A Grimes news release (and a news release from Progressive Change Campaign note that PPP was cited by the Hill and others as having the 2012 elections'most reliable poll.
