Where were the riots when Barack Obama won? There weren't any. Republicans have not elevated their beliefs to a religion like Democrats have. What Democrats have done is brainwash their party members. That's why they like religious fanatics (i.e. behaving irrationally and emotionally when their religious beliefs are attacked).
You just perfectly defined the Tea Party. They built up a towering irrational belief system to justify their revulsion to having a black president. They did not riot but their devotion to their made-up anti-government ideology caused a great injury to our country by making it acceptable to oppose everything at any cost solely to make the president a failure. Now here's Trump, prepare to be on the receiving end of that sort of blanket opposition, the right has earned it.
