From what I can tell, your "alternative" is apparently an untrustworthy, gun-grabbing, health care insurance-mandate advocating, illegal alien "legalizing" chump for global warming zealots. Of course, he denies all that, today...
Sheesh.
Uunless, of course, you are advocating for Mitt Romney.
Given your preference, you might as well do so yourself. I'll stay in the Cain, Santorum, Bachmann camp thank you until the nominee is selected.
From what I can tell, the basis of your disapproval is that you think Gingrich is lying. I won't bother trying to change your mind on that one, though I will tell you my personal opinion, which is that he is the only candidate that is looking at some of the problems we are facing honestly. Immigration would be the prime example. Once you seal the border, get rid of entitlements and enforce the existing laws, there is still the problem of the millions of immigrants who are already here. Ignoring them won't make them go away. Nor will assuming that they'll just "leave on their own." They won't.
On top of that, you are sorely mislead about his health care and environmental positions. Sounds like you are getting your information from his political opponents, without doing any research for yourself.
Finally, I have no idea where your getting he "gun grabbing" accusation from. Gingrich gets an "A" rating from the NRA, and addressed this year's leadership conference.
