In addition to its use achieving desired electoral results for a particular party, gerrymandering may be used to help or hinder a particular demographic, such as a political, ethnic, racial, linguistic, religious, or class group, such as in Northern Ireland where boundaries were constructed to guarantee Protestant Unionist majorities. Gerrymandering can also be used to protect incumbents. Wayne Dawkins describes it as politicians picking their voters instead of voters picking their politicians; Thomas Hofeller, the Redistricting Chair of the Republican National Committee, stated "Redistricting is like an election in reverse. It's a great event. Usually the voters get to pick the politicians. In redistricting, the politicians get to pick the voters." in reference to the 2000 Census.
