Bernie Sanders is replacing his state director in the critical early-voting state of South Carolina. Sanders’ presidential campaign tells The Associated Press that Jessica Bright now heads the campaign in South Carolina. Bright had been Sanders' deputy state director and previously was political director for Democrat Joe Cunningham's upset win in South Carolina's 1st Congressional District last year. Bright replaces Kwadjo Campbell, a former member of the Charleston City Council. Sanders’ campaign co-chair Nina Turner tells The Associated Press that, "Campaigns aren't for everybody, and we wish him well."

MANCHESTER, NH – Julián Castro's presidential campaign is closing down his presence in New Hampshire. The last day for Castro's New Hampshire team is Nov. 11, according to a person familiar with the campaign's plans, who spoke on condition of anonymity. The person did not say how many staffers were being laid off. The move comes as some in the crowded 2020 Democratic field reassess their operations in the early voting states. The campaign for California Sen. Kamala Harris also moved last week to largely end her effort in New Hampshire by laying off all the campaign's field organizers in New Hampshire alongside plans to close three field offices.

Biden said he would overhaul health care nationwide without "increases in taxes for the middle class. The former vice president has promised not to "abandon" Obama's signature health care law. The 37-year-old also offered a veiled swipe at Warren, Biden and Sanders — all in their 70s — by chiding candidates for being content to "wait for action." Warren supporters erected a giant likeness of Bailey, the senator's golden retriever.

Warren says that, far from having boxed herself in politically, she's been working on her health care plan for months and still sees it as a winning issue. "You're going to get health care with no premiums, no deductibles, no fear of bankruptcy if you have a health emergency." Sara Collins, vice president for coverage and access with the nonpartisan Commonwealth Club, said the key involves changing how the health care tab is divided up among employers, government and individuals. Unlike Warren, Sanders has already released payment options, including higher taxes on wealthy Americans and an employee payroll tax of 7.5%. But that would give federal authorities more control over employee health costs than employers, potentially affecting jobs.
