There is no way to ever avoid deal making or bargains in any system where negotiation or compromize is involved.
It's part of the price we pay for freedom.
It is also a byproduct of the fact that the House or the Senate have to get agreement on something for a law to pass.
Either representatives have the ability to argue and bargain to hopefully arrive at a good solution to a problem, or we have a dictatorship.
The failings and virtues of any representative government are inherent in the freedom of choice.
