I believe that if Obama is elected for a second term it will be the end of free elections in the USA. I believe there will be some occurrence that will cause the institution of Martial Law and Obama will suspend the Constitution indefinitely.
"The tree of liberty must be refreshed from time to time with the blood of patriots & tyrants. It is it's natural manure." Thomas Jefferson.
In my opinion,this is what will happen if Obama wins the 2012 election.
I hope to God I am wrong but......
YMMV
Funny thing is, the left was saying the same about Bush not so long ago. They were wrong too.
