All we need to do is recall what happened in Egypt and other nations during the "Arab Spring". The people who rose up and overthrew their governments did so with the help of the internet - Tweeting, texting etc. The internet allowed the people to organize. Without the internet, they would have failed.
Now fast forward to November 2012. What if Obama loses, but decides he does not want to leave? After all, he still controls the military for another 2 months. And if he has the power to shut down communications, the people would find it nearly impossible to organize and rise up effectively.
Obama would have control of the military, and all communications. He has his socialist friends in almost every office and agency, all committed to him. So tell me, exactly WHAT would stop him from hijacking the government and pulling off a real coup d'etat? No other leader in the history of the world has ever had the power he would have!
I am not saying he WOULD use the power that way. But he COULD. And over the last 4 years, his attitude has been one of tryanny, not leadership - by-passing Congress with Executive Orders (some of which are illegal) and taking matters into his own hands. Why would he suddenly just "give up" if he loses in November?
We, the People need to stop this unwarranted and dangerous seizure of total power. Power corrupts, and absolute power corrupts absolutely.
