she was forced to withdraw by threats we do not know ,and forced to keep silent that we do not know
I agree with you - she was threatened. Unfortunately I suspect part of the threats were from the GOPe.
Case in point... when democrat operatives attempted to burn the Wasilla Bible Church mere days after the 2008 election. Those thugs were heading out of town after weeks of digging (and inventing) dirt on Palin and her family during that campaign.
The church burning was conducted while dozens of church members and families were inside. As accelerant was found at the entrances, the message from the dems was, "we intend to kill you."
No one will ever convince me that wasn't a terror attack planned and executed by 0bama sympathizers.
Notice the whole issue was quietly swept under the rug?
