 First-past-the-post minimizes the influence of third parties and thus arguably keeps out opposition.Critics of two-party systems believe that two-party systems offer less choice to voters, create an exaggerated emphasis on issues that dominate more marginal seats, and does not completely remove the possibility of a balanced chamber (or hung parliament), which can also give undue power to independents and lead to even greater instability.A safe seat is one in which a plurality or majority of voters, depending on the electoral system, support a particular candidate or party so strongly that the candidate's election is practically guaranteed in advance of the vote.
