GUEDES, Nuno. Left-right: the ideological positions of PS and PSD parties (1990-2010). []. , 80, pp.95-116. ISSN 0873-6529.  https://doi.org/10.7458/SPP2015807849.

Several studies report an ideological convergence of the main parties in the European countries. In Portugal, analyses of PS and PSD frequently consider them to be identical or extremely similar parties. This article is an attempt to test these ideas looking at the positions in left-right scale from 1990 to 2010. We use secondary data with the evaluations of specialists, citizens and election programmes. The results indicate that PS and PSD tend to be closer than what has been observed in other European countries, but there isn’t an approach. However it is possible to conclude that there is a common evolution to the right.
