For pete's sake, the two of them are combined getting nearly 50% of the popular vote added together, and Romney barely gets past 39%.
The Democrats did this in 1972 and 1976 against George Wallace. Classic reverse case. A conservative, anti establishment candidate was racking up a terrible storm in state by state, taking on the moderate/liberal Dem. ESTABLISHMENT, so they got behind closed doors and they said "you take Wallace on this state and the rest of us will stay out", and "you take Wallace down in this state (i.e. Carter), and the rest stay out", etc. etc. It was called the ABW movement. Anybody but Wallace. And for all intents and purposes, it worked.
The “ABW” strategy within the Democrat Party may well have been in 1976 rather than in 1972, I forget which, although I do know in 1972 he was stopped by an assailant in a shopping center. So I assume their anti-Wallace powows were in 76.
Right now with the delegate count, Romney is playing a disciplined and smart campaign for himself, ammassing over 50% of the delegates with just 40% of the vote. the two of them together (Newt and Rick) could stop that if they come together and one of them steps back for the betterment of the country.
