This is true for Northern Europe’s large social-democratic parties (Denmark and Sweden) but also for parties that attempted to “modernize” themselves by combining socialism and liberalism (the UK and Spain), and even for Europe’s more traditional socialist parties (Belgium and France), which, despite local successes, have found it difficult to re-gain national power. Meanwhile, those parties that intend to move left, such as die Linke in Germany, risk being overwhelmed by the radical anti-capitalist left.
而这一解释不但适用于对北欧地区那些较大的社会民主政党（比如丹麦和瑞典），更对那些试图通过将社会主义和自由主义相结合来“革新”自己的政党（比如英国和西班牙），甚至对那些在地方选举上大获全胜，却一直难以重获全国政权的比较传统的社会主义政党（比利时和法国）也是有效的。同时，一些尝试向左倾的党派，如德国的左翼党，也面临着被更激进的反资本主义左翼党派所压垮的危险。
