The US Senate Democrat changed a rule that requested to have 60 Senators to end a roadblock to a US Presidential nomination..
Practically if President Obama wanted to elect a judicial or executive representative (except US Supreme Court), unless he had 60 Senators, the nomination could be blocked by a small minority (read Tea Party). It has been a symbol of the US Congress gridlock and survived dozens of attacks, but not today.
This is just a small insight on what is happening in the Congress in trying to decrease the gridlocks caused by the Tea Party and in preparation for the new showdown in January.
If this pattern continuous and its ramifications get pick up by investors we could see an early start of the Stock Christmas rally.
