Barack Obama...

“… to the degree that we brook no dissent within the Democratic Party, and demand fealty to the one, ‘true’ progressive vision for the country, we risk the very thoughtfulness and openness to new ideas that are required to move this country forward. When we lash out at those who share our fundamental values because they have not met the criteria of every single item on our progressive ‘checklist,’ then we are essentially preventing them from thinking in new ways about problems. We are tying them up in a straightjacket and forcing them into a conversation only with the converted. Beyond that, by applying such tests, we are hamstringing our ability to build a majority. We won’t be able to transform the country with such a polarized electorate.”
