Socialized Health Care is a big one. Single payer in particular: back when Obama was able to force through the ACA, he was unable (or unwilling) to get support for a single payer system a la Canada or much or Europe, and instead settled for a plan that was basically designed by conservatives a decade earlier. A truly liberal party would have fought for single payer, rather than the halfway-but-not-enough plan we got.
