How to make this a 2-man race

Newt Gingrich, Rick Santorum, Rick Perry, and Jon Huntsman all seek to be the same thing: the anti-Romney. Well, there is a way in which all could get promotions from their current jobs and beat Romney. That is, team up. Ron Paul is not interested in joining such an effort, but conservatives can be assured he won't be President. So, here is my remedy. Rick Santorum, Rick Perry, and Jon Huntsman all drop out of the race and endorse Newt Gingrich. Gingrich is respected amongst all the candidates. Then, make the race one between Gingrich and Romney. Then, when Newt Gingrich wins the nomination, he picks Rick Santorum for Vice President. Santorum provides Gingrich with a conservative running-mate from a swing state with appeal to social conservatives. Furthermore, Santorum is a young guy which helps balance the ticket and enable him to run for President in the future. Then, if the Gingrich/Santorum ticket wins, Rick Perry should be Gingrich's pick for agriculture secretary. Perry served as Agricultural Commissioner in Texas before serving as Governor. Jon Huntsman should then be Gingrich's pick to be secretary of commerce. As a Former Governor of Utah who helped that state's economy, he is qualified for the job. Furthermore, if he decided to run for President again in the future, he could run as someone with foreign policy, private sector, and governmental economic credentials. The chances of all this happening? Well, 0%. But it could work. Newt Gingrich is the best equipped to run against Romney, and he is also the oldest of the 4.
