The common people is not a unified block. Some will react as you suggest, but not all will. If unemployment continues to spread and people get more frustrated and this administration continues to deliberately fan the flames of class warfare, then it wont take a lot of people to stoke up the kind of chaos I believe Obama wants to see.
Obama doesn't really want chaos. If chaos happens, who will the people blame?
Well, the last time we had national chaos and rioting in the streets was in 1967 and 1968. People blamed the Democrats and Nixon got elected. Go back earlier. In 1930-1932 we had economic chaos. Who did people blame. Hoover and the Republican Congress.
When chaos happens, the Party in Power is blamed. Obama's attempt to blame Goldstein (Bush) will fail because people elected him to fix the problem. If things are only getting worse and if people are getting angrier at each other because of what he is doing, voters will turn on him and his party. They will turn on the activists, such as ACORN, who supported him, too. The day will come that a person will deny three times that they were ever in ACORN.
Trust me. You will thank God that John McCain lost this election. What is happening now is poetic justice and Monster Karma that is happening to the Democrats for all the Bush Hate they trafficked in. Now it comes back to bite them in the ass.
Best,
Chris
