1. In a country there are 20,000,001 Conservatives and 19,000,001 Liberals and 1 moderate. The liberals are at one end of the spectrum, the moderate in the middle and the conservatives at the other. Three people run for president, a conservative, the moderate and a liberal. The country uses a voting method where candidates are not allowed to vote. So the positions of the 39M voters and 3 candidates are shown below, left to right. Voters prefer candidates close to...
