Yes, except for the places where he doesn't make sense. Mostly this is in foreign policy, where he shows traits that are close to insane. For this reason, he is not and never has been a serious candidate.
Back to the subject: The most important characteristics of the Republican nominee are (a) the ability to get conservative legislation introduced and passed in Congress, and (b) the steadfastness to stick to his conservative principles in the face of huge and strident pressure to change or abandon them.
These two points assume, of course, that he is conservative to start with. Red flags have been raised for both Newt and Romney: Newt for his tendency to experiment with "new" ideas that can too easily morph into modern liberalism, Romney for Romneycare and his statements that, while such universal health care is not good for the nati0on, it IS good for Massachusetts. Being half right in this instance, is NOT a good thing. At best Romney's adventure with Romneycare shows a possible tendency to NOT stick to conservative roots; at worst, it shows a streak of liberalism.
Any Republican from the last 10+ years is suspect, of course, since the Republicans of 2000-2006 spent like big-govt liberals and approved more than one liberal program. So for any Republican from that period (including Newt and Romney), we have to assume they will change. Unfortunately this itself violates Rule (b) above - the steadfastness to stick to his guns. And assuming that ANY politician will change (as Reagan did) is chancy at best.
In other words, we have two flawed candidates in Newt and Romney, and no other real possibilities for President in 2012.
Whch one of them should we nominate? Newt or Romney? Which will fulfill better (however shakily) the two requirements above?
