I love what you wrote? Is that a famous quote Ive not heard of?
For markets to reach balance efficiently, people must have accurate information. Mix the MSM lies (and many who follow and believe it) with the fact that liberals will bet emotion rather than the facts (a second distortion) ... ... that's just pure opportunity.
Bush v Kerry was good betting based on the political betting markets. Trump v Hillary was also very good ... ... ... because you knew the conventional wisdom had its head up its butt lying to itself :-)
