John Boehner reelected as house speaker

Contrary to popular belief, tyranny is not permanently bound to civilizations of the past. Tyranny can actually be considered to be present in the USA too.
Today John Boehner won election to the greatest leadership position in the House of Representatives: the Speaker of the House. Boehner won by a smaller margin than expected as some republicans even voted for another leader. As speaker of the House of Representatives it is expected that he would be popular among the other representatives as corporation, respect and belief in a leader is important. Although, in a tyranny respect for the tyrant is not essential. In fact, the tyrant's best plan of action is to have his citizens or constituents as separate from him as possible. This works to his advantage as being separated from citizens furthers the possibility of being taken over by them. However, the tyrant must also retain his power. He does this by ruling over his citizens and forcing them to support and like him.
This balance is seen in Boehner's leadership in congress too. Boehner is a radical a republican he can be while receiving just enough votes to remain elected and continue to hold power.
This may not be quite enough information to declare Boehner a tyrant even though he may be perceived as one (for other reasons) by many democrats.
