I've resisted passing along any "make sure the Democrats put this in their party platform" action alerts, as I'm generally more interested in telling Congressfolk to enact policy, but I'll point you to this one from National Nurses United, which helps you tell the Democratic Party to put Medicare-for-All in its 2016 platform. Why? Because Medicare-for-All, like Medicare, is actually fairly popular across the political spectrum -- NNU's petition says 58% of Americans support a single-payer, Medicare-for-All health care system, and that number is in line with virtually every other poll I've ever seen. Of course, popularity isn't the only criteria for enacting policy; it also has to be good policy, and single-payer health care systems all over the planet provide better care at lower cost than our current system of privatized health care (and mandating citizen participation in that privatized system). Don't believe the hype that Medicare-for-All will make it harder to get good care, or that Medicare-for-All will add to the bureaucracy -- certainly not when our system already does both these things quite well! (Yes, private health insurance corporations have bureaucracies, too.)
Finally, H.R. 2680, the HALT Campus Sexual Violence Act, might have an awkward acronym, but it would do a lot of good -- it would provide more federal funding for investigations of Title IX and Clery Act violations relating to sexual assault on college campuses. (The Clery Act, passed in 1990, mandates that colleges participating in federal financial-aid programs disclose data involving crime near or on their campuses. Jeanne Clery was raped and murdered at Lehigh University in 1986; her parents sued the college, arguing that if Ms. Clery had known about the rash of violent crimes afflicting the university in previous years, she wouldn't have attended the school, and thus wouldn't have died there.) H.R. 2680 would also permit sexual assault survivors to sue universities under the Clery Act as well as Title IX, would revamp the penalties colleges face when they violate Title IX and the Clery Act (for these penalties are either too onerous or too lenient to be effective at present), and would survey students anonymously across the country about sexual assault, and publish the results of those surveys. Hence CREDO helps you tell your House Reps to support the HALT Act.
