"None of those [Gingrich, Reagan, the 2 Bushes, McCain] individuals shared much in common with the philosophy of President Obama." -M.T.
False! Except for Reagan (& at times Gingrich), the other Republicans all supported Big Government (are "Statists"), just like Obama. Only Reagan (& at times Gingrich) openly advocated a shrinkage in the size & scope of the Federal Government. Reagan was strongly opposed by the GOP Establishment.
The GOP needs to make a decision: do they want a small, Constitutional Federal Government, sound money & a balanced budget or not? If the answer if no, then it's time for the Tea Party & others who support those aims to abandon the GOP & let it die like the Whigs died in the past.
