Yesterday's public waffling by Sen. Dean Heller (R-Nev.) put the healthcare bill in sudden danger that almost certainly will mean notable changes.
Assuming Vice President Pence as tie-breaker, the White House and Senate Majority Leader Mitch McConnell can only lose two Republicans,and at least eight have expressed misgivings about the bill as currently written.
We asked a high-level source close to Senate leadership for a danger gradient of who is most at risk of defecting. From the source's texts:
1. Sen. Susan Collins of Maine: "She wants to remain engaged in negotiations so makes sense not to foreclose the option to vote 'yes.' But there is no way she'll vote for this bill, just on pro-life protections alone."
