One of democracy’s ideals is egalitarianism: Each person gets one vote, and all votes are equally consequential, so that all people have equal power over the world. For that reason we consider it improper for one person to vote twice in the same election. But then shouldn’t we also consider it improper for dual citizens to cast votes in two different places?

It’s true that dual citizens vote in different elections, but they’re still exercising twice as much power over the world as other voters. And it’s true that power is already unequally distributed among the world’s voters, but this is no reason to shrink from the ideal.

The fact that a dual citizen has the legal right to cast two ballots doesn’t mean that this accords with democratic principles. Suppose that Texas passed a law saying that any native-born Texan can vote in Texas, regardless of where he currently lives. Then a Texan living in Pennsylvania could cast ballots in both states, whereas a native Pennsylvanian could vote only once. This might be legal, but we would object morally to the unfairness of such a law.

Given the unequal influence of the world’s nations, one idealistic way to equalize power among all voters would be to give everyone a right to vote in every election, everywhere. This would give each of us an equal amount of power over the world. “That vision remains pretty visionary, we concede,” write Robert E. Goodin and Ana Tanasoca. “Still, visions matter.”

Eleven fenmen from the Isle of Ely, being employed by Sir John Griffin, in training a part of his park at Audley End, went one evening to the Inn called The Hoops, to drink. After getting a little spirited, they told the maid, they would give sixpence each to fetch them as much beer they could drink, in half-pints out of the cellar; if they tired her, she was to pay for the liquor; if she tired them, they were to pay for the whole. The girl accepted the bet, although she had been washing all the day, and drew them 517 single half-pints, before they gave out, which were all drank by the said men. The distance from the room where they sat, to the tap, was measured, from which it appears she walked near 12 miles in fetching it; and the quantity of liquor drank by each man was about three gallons in three hours. The above is the real fact.

$25 DOLLAR reward will be paid for the detection of the cowardly thief, who is in the habit of sneaking and creeping up to the door of No. 10, City Hall Place, and stealing the Sun newspaper from under the door. The above reward will be paid for the information left at the Sun office: and a regular roasting is promised the low, guilty, nigardly thief.
