选举是欧美资产阶级代议制度的主要特征。阅读下列材料：

材料一  任何行政官员都不应根据人民的选举来任命。议会中掌握着多数的政党通常将任命它自己的领袖；各大臣自然均由为首的大臣选任；而为首的大臣本人，尽管实际上由议会指定，但在一个王国政府则应正式地由国王任命。美国宪法规定四年一度由全体人民选举总统，当国家的最高职位要由每数年一度的普选来决定时，两次选举之间的整个时间将消耗在竞选运动当中。

材料二  通过 1832 年议会改革，资产阶级取得了选举权，但政权仍在贵族手中，资产阶级仍处于从属地位。工人阶级在争取改革的斗争中出力最大，结果却一无所获。1832 年改革是一次和平的改革运动，打开了通向民主之路的大门，但民主的道路并没有走完，它还要经过几代人的艰苦努力，才能最终完成。

材料三  帝国议会选举实行了当时很先进的普遍、直接的男子国会选举权，每个 25 岁以上的德国男子都拥有选举权，参选率从1871年的51%提高到1921年的84.9%。以工人阶级为基础的社会民主党人就是通过这一合法渠道从帝国政治制度的外围进入内院的。不过国会无权选举帝国总理及其政府，这仍是皇帝的特权。
