Now, as in Hal's answer, the relative mass of the planet and its star does make the center of mass, the barycenter, of the planet-star system a point that is different from the center of mass of either body alone. This will cause the star to appear to wobble as its planet moves around it.
Gerrymander definition, U.S. Politics. the dividing of a state, county, etc., into election districts so as to give one political party a majority in many districts while concentrating the voting strength of the other party into as few districts as possible. U.S. Politics. to subject (a state, county, etc.) to a gerrymander.
It is hard for me to see any good in gerrymandering. It is a process that is done in order to rig the political process to help the party that is doing it. Doing this is selfish and (in my view) unethical and it results in a more partisan and less unified country.
