Joe Shipman reports that Hopewell Township, New Jersey, just had a tied election for councilperson (3925 votes each, 4 ambiguous absentee ballots currently being scrutinized by a judge). If it is still a tie after the judge's ruling, there'll be a new election.

**Old Challenge** (Joe Shipman). On the West Palm Beach ballot of the US
Presidential election, it apparently turned out to be a big advantage for
the Republican candidate to be listed first. Can you come up with a fair
procedure for allocating ballot order from year to year between the two
major parties, if you assume that being first is an advantage?

**Answer** (Alex Glasser). Find two equally favorable spots and use the same
spots every year. Put the Republican in the upper right and the Democrat
lower on the left. "Every year the voter would know where their candidate
would be without change (because some say the change in location of the
name threw some voters off)." And of course it is preeminently appropriate
to have the Republican on the right and the Democrat on the left.

If you need to put one party on top, Joe Shipman notes that you would need a long-term cycle to be fair on local, state, House, Senate, and Presidential elections, perhaps an 8-year cycle such as DRDRRDRD.

**International Mathematical Olympiad **for high school students will be hosted
by the United States next year, July 8-9, 2001. Volunteers are needed:
teachers to run the exam (contact Susan Schwartz Wildstrom
<ssw@umd5.umd.edu>) and college students to live with foreign competing
high school students for two weeks before the IMO (contact Eric Walstein
<ewalstei@mbhs.edu>)

**Riddle** (Jacob Sturm). What is greater than God, more evil than the devil,
the poor have it, the rich want it, and if you eat it you die?

**New Challenge** (Timur Dogan). Which branches of mathematics or types of
problems are the most counterintuitive?
