You are mostly right, except the violent overthrow part. They have successfully infiltrated our educational system, used unions and their dues to support extreme leftists, used our tax money to support leftist groups (Acorn, etc.) and propaganda, and allowed foreign influence into our elections. Two slogans for 2012: 2 + 2 = 4 and Yes, I Can!
On with the investigations and prosecutions in 2011.
I wish I was wrong about violence on their part. More than one union President in the past 2 years has suggested that we can go along peacefully or else...
Several recent pieces in the Huffpo have suggested that violence is on their table.
The head of the teacher’s union in New Jersey has advocated Governor Christi’s death.
Penn (Hillary’s Pollster) even suggested that another event like the Oklahoma Bombing is just what Hussein needs to reconnect with the people.
I am quite certain that they are not willing to go without starting some kind of violence and will not hesitate to use it to advance their “Progressive Agenda”.
