In representative democracies, gerrymandering (/ˈdʒɛrimændərɪŋ/, originally /ˈɡɛrimændərɪŋ/)[1][2] is the political manipulation of electoral district boundaries with the intent to create undue advantage for a party, group, or socioeconomic class within the constituency. The manipulation may involve "cracking" (diluting the voting power of the opposing party's supporters across many districts) or "packing" (concentrating the opposing party's voting power in one district to reduce their voting power in other districts).[3] Gerrymandering can also be used to protect incumbents. Wayne Dawkins describes it as politicians picking their voters instead of voters picking their politicians.[4]

The cartoon was most likely drawn by Elkanah Tisdale, an early-19th-century painter, designer, and engraver who lived in Boston at the time.[9] Tisdale had the engraving skills to cut the woodblocks to print the original cartoon.[10] These woodblocks survive and are preserved in the Library of Congress.[11] The creator of the term gerrymander, however, may never be definitively established. Historians widely believe that the Federalist newspaper editors Nathan Hale and Benjamin and John Russell coined the term, but there is no definitive evidence as to who created or uttered the word for the first time.[12]
The advantages of this method are that it allows a certain amount of human intervention to take place (thus solving the Colorado problem of splitline districting); it allows the borders of the district to follow existing jagged subdivisions, such as neighbourhoods or voting districts (something isoperimetric rules would discourage); and it allows concave coastline districts, such as the Florida gulf coast area. It would mostly eliminate bent districts, but still permit long, straight ones. However, since human intervention is still allowed, the gerrymandering issues of packing and cracking would still occur, just to a lesser extent.
The efficiency gap is a simply-calculable measure that can show the effects of gerrymandering.[63] It measures wasted votes for each party: the sum of votes cast in losing districts (losses due to cracking) and excess votes cast in winning districts (losses due to packing). The difference in these wasted votes are divided by total votes cast, and the resulting percentage is the efficiency gap.
Senate constituencies were created by grouping all lower-chamber districts in a region, or by dividing a region into two constituencies of contiguous lower-chamber districts. The 1980 Constitution allocated a number of seats to appointed senators, making it harder for one side to change the Constitution by itself. The opposition won 22 senate seats in the 1989 election, taking both seats in three out of 19 constituencies, controlling 58% of the elected Senate, but only 47% of the full Senate. The unelected senators were eliminated in the 2005 constitutional reforms, but the electoral map has remained largely untouched (two new regions were created in 2007, one of which altered the composition of two senatorial constituencies; the first election to be affected by this minor change took place in 2013).
This system has become known as the three-phase (τριφασικό) system or the baklava system (because, as baklava is split into full pieces and corner pieces, the country was also split into disproportionate pieces). The opposition, being composed of the center and the left, formed a coalition with the sole intent of changing the electoral law and then calling new elections. Even though the centrist and leftist opposition won the popular vote (1,620,007 votes against 1,594,992), the right-wing ERE won the majority of seats (165 to 135) and was to lead the country for the next two years.[112] 2ff7e9595c
