The ability of Congress to dictate what is "abuse of power" and then bring impeachment charges, or using the threat of impeachment on such trivia effectively makes the POTUS subordinate to Congress, if and when the Senate might be aligned with them.
This is a very different situation than requiring criminal activity as grounds to impeachment, and changes the balance of power entirely. Were it to be allowed.
All of the Senate, Congress and POTUS should be strictly subordinate to the will of the people of the US, through the elections.
Except the system was original designed such that the President is not the representative of the people but it's been bastardized over the years. The congress is actually the representative of the people which is why they have the power to impeach. Even the Senate as it stands today is not how it was intended to be. Anyone who truly believes in the constitution and looks at how it used to be and how things have changed ever so slowly decade by decade should be concerned that both houses are slowly being subjugated by the expanding powers of the presidency. The country is ever so slowly marching towards having a "king".
"As conceived by the framers of the Constitution, the House was to represent the popular will, and its members were to be directly elected by the people."
The president was intended to be voted in by electors, not the public. He was to basically be the states representative. As someone who has come to see the constitution as the founders designed it as far superior and more important that anything else in keeping the country together, the state of things today greatly concerns me when it comes to the future of the country. It is slowly devolving from a country where states rights were highly important, to them becoming subjugated by the national government more and more.
So I'm sorry, but I believe impeachment should be used as it is and should in fact be used more often to keep not just the president, but members of both houses (and judges although that doesn't seem to happen much) more in line. This current impeachment has made me reflect a lot more on the past and I've come to believe Clinton, despite liking him regardless of all his "faults", should have been removed from office. Even though some of us pretty much figured out that Bush went into Iraq (based on a global "plan" that had been drafted up a year or two prior to his coming into office by many of the people in his administration) under false pretenses, I can't remember if it became public knowledge while he was still in office in which case he should have been impeached as well. And I must say I've come to like the guy since he's been out of office and he did some good things as well as the bad. Obama, I didn't pay too much attention to his term as I had more important things going on in my life at the time so don't know if there were things there for him. In other words, regardless of party, if they violate the "public trust" in some way, "off with their heads" as far as I'm concerned. Maybe if enough of them (all of them) get thrown out they'll start to take it more seriously and do what's right for the people instead of themselves.
"In contrast, members of the Senate were appointed by the states until the ratification of the Seventeenth Amendment (1913), which mandated the direct election of senators."
"James Madison, paraphrasing Edmund Randolph, explained in his notes that the Senate's role was "first to protect the people against their rulers [and] secondly to protect the people against the transient impressions into which they themselves might be led."
In this situation, I see the Senate currently protecting the president as opposed to protecting the "people". The senate has devolved into nothing more than a second House instead of what it was really meant to be. It has become a shadow of what it once was and I for one would like to see it return to what it was meant to be. A bullwork against things like the dangers of populism. The only branch that's still able to stand up and do what's right for the most part as opposed to what's popular or by being heavily influenced by the people or the other branches, is the supreme court and that's greatly concerning.
IMO that amendment was one of the worst things that could have happened and the way things operate today bear that out. It should be no wonder nothing gets done anymore and it's all about keeping their jobs and using all the voters as pawns in their games.
One thing I find interesting is that people want someone, they choose Trump this time (I view Sanders as the far left version of Trump and would not be a good thing either), to "tear down the system". Good idea, but maybe what should happen is that it return to what it used to be and what it was meant to be. I would think that anyone that really believes in the constitution would think along those lines but I rarely see that as each side only uses the constitution to support their own agenda and is willing to bastardize and twist it for everything else.
Bottom line. IMO it should be as it was. The House is who should be voted for by the people. They are the representatives and no one else should be. I'm not against the selection of Senators and the President taking into account what the people would like, but not the way it currently is or the way it's slowly moving towards being. People are basically "stupid" and far too easily manipulated to make really good choices for such important roles IMO. Of course that also means that there would need to be some good checks and balances put in place to also ensure those making the choices did it in the best interest of the people, but if you start with the premise that it should be as I think it should, then I'm sure there are things that could be implemented instead of just going the easy "sellable" route that happens. Wishful thinking I know.
