Let's examine the evidence on the record:
Newt: Pro-life Reaganite, led the Republican Revolution, took the congressional majority from the Democrats who had held it for 40 years. And even with a democrat president (Clinton): cut taxes, cut spending, cut the national deficit, cut welfare, balanced the federal budget four years running, cut regulations, reduced unemployment, blocked socialized healthcare (HillaryCare) and encouraged the Reagan economy to flourish throughout his term and beyond. Not a bad conservative record at all. We can use some of this now!!
Newt is a veteran of the Reagan Revolution and leader of the Republican Revolution. His record of actual accomplishments shows that he was a tea party type rebel before the tea party even existed. And, your gratuitous assertion aside, he's actually a leading conservative base and tea party favorite:

Romney: Pro-abortion Reagan denier, crossed the aisle to promote abortion, gay rights, gun-control, liberal judges and actually advocated for and installed a socialist healthcare system (RomneyCare) which became the model and impetus for ObamaCare. Saddled his state with unnecessarily higher healthcare costs, busted budgets, busted Republican label, liberal activist judges, tax payer funded abortion, first in the union gay marriage, and individual mandates against the previously free citizens complete with tax penalties for non-compliance. Not even a moderate record. Romney is a liberal progressive, even to the left of his ideological ally, the late Ted Kennedy.
