If the Senate changes the House bill and then passes it, would the House have to vote on the bill again, because it was changed by the Senate?
If the Senate changes the House bill, the bill will go to conference, and the bill that comes out of conference will be voted on by both houses.
Since the bill passed the house on a simple voice vote, there is no record of who voted 'yea' and who voted 'nay.'
In the Senate, it will take 60 votes to end debate (cloture,) and there will have to be some Republican votes to vote for cloture because unlike when Obamacare was passed, the Democrats don't have 60 members in the Senate.
Then, once debate is ended, those same turn-coat slimy Republican Senators that voted to end debate are then free vote 'nay' to the actual bill, knowing that there are 51 Democratic votes to actually pass the bill. So those RINOs can then say "I'm on the record as voting against the bill" when in fact it was their cloture vote that allowed the bill to pass.
