At this point they're just flexing their muscle to see how much wiggle room they've got. A small part of me wishes votes on legislation were anonymous so our congress-critters would avoid the constraints of having to vote along party lines (and notably their campaign donors' wrath).
I would dare to say this could be a contributing factor to the state of politics and law. Essentially, laws and regulations are bought by the highest bidder.
I think many agree with me that neither religion or money should have influence on direction of politics.
For the anonymity on legislation; No. Legislation, political- and judicial processes IMHO be 100% transparent.
It's true that campaign donors have too much influence over the success of legislators, but maintaining a representative democracy is far too important to lose in order to deal with that issue.
