It's not over-reacting at all. How can anyone honestly read that interview and think Bernie Sanders is even qualified to be a Senator, much less a President. Breaking up the big banks is the centerpiece of his campaign, and yet he's apparently given zero consideration to how he will do it, the consequences of doing so, the current law, etc.?? How is that acceptable? He doesn't even seem to be aware that MetLife and AIG are currently being broken up.
On trade, another centerpiece of his campaign, he's totally unable to articulate what specifics of trade agreements are bad and that he would change. He just says they're bad and he'd rewrite them. How is that acceptable? Opposition to these FTAs is like 1/3 of all this guy talks about and he is totally stumped when asked for specifics on how he'd revise them?? Come on.
I totally understand liking Bernie Sanders. I totally understand thinking he's an important progressive voice in our political system. But how can anyone read this interview and think he's prepared to be the President of the United States?
When it comes to your bolded question, one can have asked the same question with almost all of the candidates in the race this year. It's been that bad. Just awful. Clown after clown after clown, or in some cases, folks who clearly don't have "the necessaries," like Walker or Carson and on and on, and then the shrill dyspeptic extremist head case Cruz.
All things considered, when it comes to basic competence, we have or had Pataki, maybe fat boy Christie, Kasich, Graham and yeah with a bit of a leap of faith, perhaps Rubio, and yes, the liar Hillary. I think that is about it.
