"Democrat leaders are not only out of the American mainstream, but are also out of the Democratic mainstream"

This quote by Virginia Foxx indicates that the Democratic leaders are not representing the views of most of the American people, or even most of the Democratic party. Foxx is recommending that the Democratic leaders are too far to the left of the political spectrum, and are not in line with the beliefs of the majority of the American individuals or the Democratic party. This might be translated as a criticism of the Democratic party, as Foxx suggests that the party is not representing the views of the majority of its members. Foxx is also indicating that the Democratic party is not in line with the mainstream of American politics, and is instead too far to the left. This could be seen as a criticism of the Democratic party's policies, as Foxx implies that they are not in line with the beliefs of most of the American individuals.
