How has party-line voting in congress changed in the past few years?

It has increased noticeably.  A party-line vote is one on which a larger part of Republicans vote one way and a lion's share of Democrats vote another. A bipartisan vote is one in which a larger part of Republicans and a dominant part of Democrats vote a similar way.
