Only In An Election Year

It amazes me that when a major election year rolls around, that incumbent politicians as well as those seeking to unseat the incumbents begin the heavy discussions of issues that matter to the people of this country. Maybe I am a huge cynic when it comes to this, but I think it sucks that the incumbents and political hopefuls only seem to care about matters of healthcare, social security, employment, and education when they are trying to get (or keep) their jobs.
I propose that we revise the election system in this country. Make it a "get it done or get the hell out" system. If you promise (make a campaign promise) to solve the healthcare problem, and do it, you keep your job this round. If you fail to do anything significant, you're out. No impeachment process necessary. Donald Trump gets to walk up to you and say "You're Fired." This kind of conditional election system will either cut down on the number of campaign promises made or it will strongly motivate an elected official to actually do what they promised to get elected. Of the remaining people jockeying for the big chair in the White House, they all have and will continue to tell us what we want to hear from now until election day. But what will they actually do when they get there??
My hope is that they will actually do something significant to help the people of this country, but my cynical money is riding on believing that they will do little to nothing. God, I hope I'm wrong, but I fear I'm right.
