I somehow think that the House will abandon its bill and add amendments to the Senate version. I think this because the Senate used a motion to strike and insert for its bill. A motion to strike and insert strips the old language from the legislation and allows new language to be written in. In this case, the new language was added by an amendment.
This strike and insert motion was applied to H.R. 3590, which originally was the Service Members Home Ownership Tax Act of 2009.
The Senate bill contains a tax provision, which must start in the House. But, the Constitution allows the Senate to add tax language through an amendment (U.S. Constitution, Art. I, section 7).
Given the massive giveaways in the Senate to get 60 votes, it is unlikely that the House will step in the way. Especially given the amount of money that health care industry contributes to political campaigns.
