Talk radio shouldn't be who the people turn to for political leadership. It is supposed to be our politicians -- that is why we elect them, right? So the two real problems are this:
1) Even assuming that McConnell is right about us "not understanding" how things work, the fault is that of both he and Boehner, and the members who elect them. The positions of Speaker and Majority leader have become about who is best at working tricking legislative details, and working intra-chamber politics. The idea that those positions should be about communicating effectively with the American people seems to be an afterthought at best. Neither McConnell nor Boehner is/were good at framing issues for voters, nor did they even seem to think that was important. Apparently, we were supposed to just "trust them" without them ever providing clear communication back to us. Ryan, at least, seems to understand that function of the Speaker better than any other those yahoos, and is at least attempting to become sort of a party spokesman on substantive issues. McConnell still doesn't seem to care, and is a crappy, mush-mouthed public speaker even when he does attempt such communication.
2) The biggest problem, though, is the excessive delegation of authority by Congress to the executive branch. They pass major legislation that routinely gives "the Secretary" wide latitude in interpreting and implementing the law in question, which essentially amounts to a delegation of the law-making function to the executive branch. And once that power is delegated, it cannot be overrriden absent passage of an entirely new law. So, the balance of powers that we all learned about in school is much more of an illusion than it is reality. That's not really the fault of the current Congress -- Congresses have been delegating that authority for decades. But I don't really hear much about a movement to scale that back, nor (see point 1) does our political leadership emphasize that structural problem when communicating to the American people.
Personally, I would love to see a Presidential candidate push for a law stating that no substantive regulation that normally would go straight into the Federal Register/Code of Federal Regulation is effective unless and until it is ratified by both Houses of Congress, and that this law applies to all current laws in effect as well as to new legislation. Restore much of the lost Congressional authority in one fell swoop.
