Many thanks to all those who took part in my quick quiz. Most people got the right answer, but quite a few got wrong answers.
Here's the full SP. The question was: Which of the following has nothing to do with the US Presidential election?
The correct answer was 519, which was a random number I thought of, and then checked on Google to confirm it had nothing to do with the election. (Although you could argue that if a Presidential candidate won all the states except Arizona and Louisiana, they would have 519 college votes. But it's rather unlikely.)
The other potential answers were:
527 - "A 527 group is a type of American tax-exempt organization named after a section of the United States tax code, 26 U.S.C. § 527. A 527 group is created primarily to influence the nomination, election, appointment or defeat of candidates for public office." - Wikipedia
538 - is the total electoral college votes up for grabs in the US Presidential election.
270 - is the number of electoral college votes that a candidate needs to win the election.
Again - many thanks for your participation.
