After my piece went up, the non-partisan Brookings Institution released a report (link here) indicated that 15 million Americans would immediately lose their health insurance under the proposed law, a figure that ultimately would rise to 32 million per year.
Several hours later yesterday, Republican Senator Susan Collins said she was likely to vote "no" on the bill (source here) and GOP Senator John McCain said he's a definite "no" (source here). Given Republican Senator Rand Paul has already said he's a "no" vote, that means the GOP repeal effort, aka Trumpcare, is almost certainly dead until after the 2018 midterms, at least.
If this holds, it will be a resounding victory for the American people and a stinging defeat for Trump. Ding dong the bitch is dead.
