The Democrats don’t need all of their senators to vote for the reconciliation bill to modify their health-care legislation. That means that nine Democratic senators will be able to vote against the bill. Given its unpopularity, I expect several of the senators to do so. But their no votes have the potential to put some House Democrats in a bind. If Senator Webb of Virginia votes against the bill, for example, doesn’t that increase the pain of a yes vote for the three vulnerable House Democrats from that state? And the same logic applies to several other states.
