I know that there is a counter-argument made by some on the Democratic left that a closely contested nomination process will help our ultimate nominee that Clinton will somehow benefit from having to spend most of her time and campaign funds between now and next summer proving her ideological purity in an intraparty fight, like Mitt Romney in 2012 rather than focusing on her differences with the conservative she will face in the election. But neither an analysis of the current political situation nor the history of presidential races supports this.
I believe strongly that the most effective thing liberals and progressives can do to advance our public policy goals on health care, immigration, financial regulation, reducing income inequality, completing the fight against anti-LGBT discrimination, protecting womens autonomy in choices about reproduction and other critical matters on which the Democratic and Republican candidates for president will be sharply divided is to help Clinton win our nomination early in the year. That way, she can focus on what we know will be a tough job: combating the flood of post- Citizens United right-wing money, in an atmosphere in which public skepticism about the effectiveness of public policy is high.
