Why Gingrich?

It's pretty obvious that Republicans, especially conservative Republicans, have grave reservations about Mitt Romney, otherwise he would be well ahead of the pack at this time.  After all, Romney has been campaigning for this nomination for almost four years at this point, considering his run against McCain and his nonstop campaigning since?  Truth is many Republicans simply are not impressed with his record or his presentations of his qualifications. What's more they have doubts that he would hew to the conservative principles and is, in reality, a Big Government Republican in the mold of Rockefeller, McCain, Dole, Ford and all the other centrists of the past.  The grass roots Tea Party rebellion against the Obama Administration's huge overreach in healthcare and most other matters demonstrated how seriously these mainstream, largely Republican voters are about Big Government and its intrusion into individuals' lives.   Because of his actions as Governor of Massachusetts, these voters have great reservations about Romney's commitment to their Small Government philosophy.  In addition they seem also to be unsure of his oratorical skills  going up against those of Obama.  Gingrich, on the other hand, has a well documented conservative record in House -- 90% ACU voting record -- and is thought to be capable of burying Obama in the presidential debates.  His most serious negatives are a tendency to be somewhat unfocused and perhaps have too many solutions to all our many problems.  But, as things stand as of this moment,  Gingrich's strengths seem to be carrying the day an he is now the front runner.
