Seems like following party lines thus far. But I beleive there are some reps against the bill, so this is going to be close.
S .1932 is slotted for debate the entire week, and may be voted by end of week, or early next week. A similar discussion and a vote will be planned in congress.
Yes, they haven't talked about immigration (which isn't a bad thing). So, if it follows party lines, it should go thru. But there is always a chance of amendments, if some issue (immigration) becomes a thorn w/i party lines.
