"The Republicans should have "Fixed" the country when they had control"
That assumes, of course, that you assume that this country was "broken".
I don't see that. 'Twasn't perfect, but wasn't"broken". It worked. Worked well. The majority of the people were able to make a living. Some were very rich, most weren't Some were very poor....Most lived, for the most part, well. Yes, there were those on the edges who didn't, either by bad luck or (generally) by bad choices. But they had a safety net.
Now,we are bringing the middle group down, by many points, in order to raise the small percentage by a point or two. And it didn't, really, affect the affluent at all.
If anyone or anything has "broken" the country, it wasn't the Republicans. They might not have "fixed" it, but they didn't break it.
