Sen. Kyrsten Sinema (D-Ariz.) and a handful of House Democrats oppose letting Medicare negotiate prescription drug prices, which would save more than $500 billion over 10 years. (Incidentally, three of the Democrats opposing the idea have received $1.6 million in donations from the pharmaceutical industry.) The New York Times also reports that Sinema “has privately told colleagues she will not accept any corporate or income tax rate increases,” while Manchin remains opposed to the current plan’s proposed corporate tax rate.
