Why do you think political parties emerged even though most americans opposed them?
in detail plz

To divide we the people to weaken us, set us against each other with blame games and propaganda. Party loyalty blinders keep us from watching too closely what our own party representatives are doing against our own interests. 
Like professional wrestlers they appear to be bitter rivals in public but are the best of friends behind closed doors. They have led us to think that only someone from their parties can win an election. If we vote for a third party candidate we have "thrown our vote away" on someone who stands no chance of winning and let that "evil other party" candidate win. We feel compelled to vote for the "lesser" of the two evils being offered. 
Consider this: Both parties of the Senate said that the TARP bill lacked oversight to protect the taxpayer's money (concerning the original 3 page one passed by the House of Representatives). They claimed they were going to add protection and oversight to it. Then behind closed doors they added 137 pages of earmark spending and NO oversight or protection. Bush signed it and they closed the 110 Session of Congress knowing that they had an automatic pay raise in place. Both parties were involved so no evil other party blame games could be played. 
Instead they faked outrage when the AIG bonus news came out and blamed the Management for not following rules which they had failed to put into the TARP bill in the first place. Watch this video
