Regardless of what Santorum or Gingrich does, I believe like the two of them would do, I will support the Republican nominee against Obama. As I have posted before no one can claim to be for God and country, and stay neutral in this race.
I sure as Hell am not going to meekly support a man I perceive as a fascist, a national socialist. If one ignores his pandering lies and examines his past governing record, he is neither a conservative nor a loyal American.
National socialism isn't now, nor has it ever been, a part of the Republican Party's platform. This isn't the year it will be tacked on.
There are 4+ months until Tampa, and 7+ months until the election itself in November. This is plenty of time for anything to happen and alter the trajectory of this race.
I am hoping that Santorum and Gingrich hold off on doing the ‘necessary’ thing (officially endorsing Romney) and instead join with other conservatives and marshal a mutiny contra the Republican establishment. It won't be easy - they'll have to stop squabbling among themselves - but it is possible.
