I love Mark Levin. I have read most of his books.
I think the Power of the State is such that there is no "legislative" way back (at the Federal level) towards a limited government. My reading of history says that only a cataclysmic event will present the opportunity to made a sudden move back towards Liberty.
I believe when the "event" happens, the States offer they last peaceful chance to roll back the Federal Leviathan.
If you read history, true Liberty is only gained in a short period of time (a decade or less). You can't transition over a long period towards smaller government.
In other words, after a collapse, actions must be taken to quickly and relentlessly dismantle all unconstitutional parts of the Federal Leviathan. Large numbers of Federal workers must be fired and must have their pensions revoked. The courts below the S.C. must be dissolved.
For America to once again have Liberty, the counties around D.C. must become impoverished.
Deductions of revelations of the consolidations of power, arms, ammunition and rhetoric against Conservatives, would indicate that the Regime WANTS some kind of cataclysmic event. News today has Obama sending Holder's People down to Florida to AGITATE the protests against George Zimmerman.
As I ponder the title as listed at Amazon, Restoring The American Republic - given the history of other republics before us is not going to happen without the use of force.
And even then, I do not think there is a single case in history where a republic-turned Democracy ever restored itself from tyrants. They simply collapsed into oblivion.
The of course, there is what John Adams warned:
"A Constitution of Government once changed from Freedom, can never be restored. Liberty once lost is lost forever. When the People once surrender their share in the Legislature, and their Right of defending the Limitations upon the Government, and of resisting every Encroachment upon them, they can never regain it…" John Adams - letter to Abigail, 1775
