Actually, I think the Arabs would be much more apt to vote Republican or its equivalent. They are really into social conservatism.
Regardless, it would be a tough thing to advocate a democratic world government when the other governments of the world are not democratic.
Since we are speculating grandly here,however, I am going to assume that such a move would take place at some time in the distant future when democracy is universal. I think conservative ideals, as we know them in the United States, would be attractive enough to hold sway on a global scale, so that is not what concerns me.
sixmil's point about the loss of local control is important. What type of powers would be necessary to retain locally and what would be appropriate to relinquish to a global entity? My intial impression is to say financial matters like currency, trade and tariffs and possibly even some regulations in terms of laws, the environment, etc. might benefit humanity if implemented on a global scale. Everything else (including taxes) would have to stay as local as possible. The toughest issues are things like immigration and wages. If income levels around the world are more similar, than the issue is irrelvant(We don't get many immigrants from Western Europe or Japan anymore). If the disparity remains great, what to do about working conditions, minimum wages and open borders is something that would absolutely have to remain local
Revel pointed out the Tower of Babel legend is relevant to this issue. He/She is right. Although I am not a literalist in terms of the Bible(not to mention that the story no scientific sense), this story is a warning that the combined energies of mankind will only lead to disaster and division. Would some "Grand Project" of humanity to engineer that planet or some ambitious space journey lead to the destruction of our civilization? Could be.
Good stuff. Thanks.
They have history of supporting governments that enforce islamic law, I guess that could be social conservatism in some circles.

A consitutional republic would be much more desirable, but we are having a series problem preserving one here now.
