California Democrats on Friday kicked off their three-day convention with a \u0022raucous start\u0022 in Sacramento, where a wave of single-payer advocates demanded the party work towards a system that makes healthcare a human right.The gathering comes amid growing momentum nationwide for a single-payer, or Medicare-for-All, healthcare system, and as the Republican\u0026#039;s widely scorned American Healthcare Act (AHCA) is days away from receiving its potentially problematic Congressional Budget Office (CBO) assessment.In a evening rally and march that went from the capitol to the Sacramento Convention Center, a crowd of nurses and other healthcare activists urged support for SB562—the advancing Healthy California Act—which would create a universal health system for Californians, and could \u0022send a message\u0022 and \u0022be a catalyst for the nation.\u0022Of the fight for single payer, RoseAnn DeMoro, executive director of the California Nurses Association, which organized the action, thinks California Democrats \u0022cannot be in denial anymore that this is a movement that can primary them.\u0022DeMoro, who is also executive director of National Nurses United (NNU), took to Twitter to capture speeches at the rally and images of the sign-carrying marchers:.@RoseAnnDeMoro and @ninaturner for #SinglePayer, #SB562 \u0022Don\u0026#039;t wait for the Dems to lead.

So let\u0026#039;s get with it,\u0022 the LA Times reports Burton as also saying.Democratic National Committee Chairman Tom Perez, who this year beat the NNU-backed Rep. Keith Ellison (D-Minn.) for the post, also spoke at the podium. He tried to inject some levity into the situation, comparing it to Thanksgiving dinner with extended family. He appealed to party members to seek unity, saying: \u0022Donald Trump has to go. And that is why we must work together as Democrats.\u0022Tom Perez at #CADEM2017, protestors boo \u0026amp; give him a The People want #SinglePayer, #SB562 - Dems ignore at their own peril #FridayFeeling pic.twitter.com/uCwV5dr7WQ— RoseAnn DeMoro (@RoseAnnDeMoro) May 20, 2017The Sacramento Bee writes that \u0022the throng advocating for a statewide publicly funded, universal health care system snaked down a staircase behind Perez, shouting down his calls for unity.\u0022As for the the outcome of the convention, Politico reports that it will \u0022reverberate\u0022 nationwide:With President Donald Trump in a tailspin and the Republican House majority appearing increasingly vulnerable, what happens here at the California Democratic Party state convention this weekend will reverberate across the map.Featuring as many as seven vulnerable GOP-controlled House seats, this solidly blue state is key to flipping the House in 2018. But when more than 3,000 activists in the nation\u0026#039;s largest Democratic Party gather this weekend in Sacramento to forge opposition strategy and choose new party leadership, the state party\u0026#039;s internal squabbles will also be closely watched.Iowans are also hoping to underscore the importance of a universal healthcare system this weekend, with rallies in seven cities set to take place Saturday.\u0022It just shows how important it is for us to be putting out an alternate vision for what our future should be rather than just saying no all the time,\u0022 said Chris Schwartz, a community organizer with Americans for Democratic Action Iowa.
