Positive assessments of what entry to the European Union (EU) meant for Poland and for Poles increased after the 2003 vote to join and dramatically so after accession. Analysis of panel data from 2003 and 2008 shows the increase in positive assessments is related to the size of EU transfers and to increases in personal income, particularly for assessments of personal benefits. The attitude changes are also related to variables associated with individuals mostly likely to benefit from greater access to the larger Europe. The positive EU attitudes on both dimensions are related to votes for the pro-EU party that came into office in the 2007 election. In this way, the benefits from entry ‘bought’ more favorable attitudes and a more favorable government for the EU.
