First public poll since August 17th, and first poll by this company since early July. Fieldwork predates the announcements by the Prime Minister and the Minister of Finance of new austerity measures, so you can probably see this as just giving a first inkling of the likely massacre to come.
PS: 35.4% (+4.6)
PSD: 33.3% (-1.7)
CDS-PP: 7.1% (-0.8)
I'll fill you in on the other parties when I get them.
