All we need is one congress critter that is willing to buck the system, a critter that is not out to make politics in a congressional office a career. Someone unwilling to compromise when it comes to American exceptionalism, and the Constitution.
Sara Palin comes to mind.
I am afraid that it will take many more than just one member willing to buck the system, especially with ideological tilt of the press.
Reform will not emerge from DC, it must come from the people and the states. But that doesn't mean the spark to reform cannot come from Congress. Ted Cruz has had it with the rinos and rats, and may well make the case for an Article V convention of the states.
