Blue dog dems are looking at the costs and saying no. The mainstream Democratic Party needs some Republican Votes to pass the bill.
UNLESS.. they go to the differential. That differential allows less than 60 votes to win approval. Senator Schumer of New York made it clear the Democratic Party would revert to the differential if they could not get the majority vote. Senator Schumer ....... of New York..... has a huge illegal alien population the Hotel Industry needs to make the system work. The problem is what those illegal aliens are doing to the health processes in New York, soooo... he really, really, really wants that insurance bill to the point that he is flinchey and yelling. I like that.
Yes they do need Republican Support, but I don't think they will get it. Illegal aliens have to be removed from the protected, and the bill needs to go to basics which will help people go back to work.. but exclude births, or sex change operations. But there will be insurance for those items.
I would, however, point out that Schumer probably has a lot of blackmail in Congress, on Congress. We shall see.
