Due to the premise that many who would vote for smaller parties for their first choice, instead have to vote for the lesser of two evils for their voice to be heard, parties criticise each other rather than making themselves the first choice. If one party is portrayed as the enemy, then supporters of smaller parties may root for the other major party to keep them out of Parliament. A two-round system means that parties focus on giving benefits of a government including them, rather than mud-slinging so that they can make it to the second round.
