You want to know why the left has ideas and the right has discipline? Because people who like ideas and dislike authority tend to identify with the Democratic left, while people who feel threatened by new ideas and more comfortable in a disciplined and ordered world tend to identify with the Republican right. Democrats and progressives let a thousand flowers bloom. Republicans and the right issue directives. This has been the yin and yang of American politics and culture. But it means that the Democratic left’s new ideas often fall victim to its own notorious lack of organization and to the right’s highly-organized fear mongering.
