If you want to know how the priorities of a political candidate compare to the priorities of the general public, then it is helpful to read/listen to the speech that the candidate makes after a win or loss at the voting booth.
First, here is a recent list of the priorities of the general public, as provided by the Pew Research Center:
Which candidate better expressed the top priorities of the general public?
In order to defeat Obama in November, the GOP candidate needs to win over moderate and independent voters. The last time that I checked, those voters couldn’t care less where the U.S. Embassy in Israel* is located. By the way, the U.S. government recognized Israel way back when Israel declared statehood. Gingrich the historian should know that. [*Post updated: I originally wrote "Jerusalem" instead of "Israel".]
Personally, I don’t care who the eventual GOP nominee will be as long as that person can defeat Obama.
