To clarify how the electorate decides, a May survey of the Public Opinion Research Centre investigated to what extent voters were certain of their party securing sufficient votes to get into the Chamber of Deputies, and how they would behave if not fully certain about it winning seats in the Chamber of Deputies. All those who said which party they wanted to vote for (856 respondents) were asked the following question: ‘Do you think that in the coming election this party will secure sufficient votes to get into the Chamber of Deputies?’ A majority (84%) of respondents are certain that the party of their choice will, whereas 11% are not and 5% do not know.
