I have never heard of Majority watch or Lycoming college. I would just ask that those who post polling would only use reputable firms.
Majority Watch is the joint venture of a new company, Constituent Dynamics, and RT Strategies, an established and well-known bipartisan polling firm.
Constituent DYNAMICS is so new it does not even have a track record from the 2004 Elections.
Their web site is also amateur, I will only look at reputable firms thank you.
