Think Progress reports this from CNN:

More and more, Congress is acting less like a deliberative legislative body, and more like a political campaign. We’ve been seeing the politicization of every aspect of government.

Pshaw! Nothing new here.
These folks have apparently been operating under the delusion that congress has been a deliberative body anytime during the past couple of centuries.
Most vote changes have occurred in the the hallways and offices of the congressional office building; and, yes, in quite a few DC bars and restaurants. These changes as well as some that have occurred on the floor typically fall under the labels of arm twisting, back scratching and purchase rather then deliberative debate.
Don’t expect this to change. They don’t represent you.
