<human>: Give me the gist of the text in a nutshell

I have been sending out resumes lately because of drama and office politics at my current job. I've gotten an interview and have an inkling they're going to ask me why I haven't been at my current job for very long (8 months.) I want to assure them I don't job hop as soon as things start getting testy, but I think it's not the best idea to tell them that my current boss is an idiot. 

Some background on my current job:

My boss has no experience. This is his first job and he kissed ass enough through several promotions, but he doesn't know anything about management. He frequently gossips about us to other people in the department. He regularly sets the department up to fail trying to impress the higher-ups (coming at us with impossible demands, last minute projects that he's known about for months, etc.) Despite the fact that every single employee knows he's incompetent and dozens of complaints have been directed towards him, the owner likes him, so no change there. 

There are almost no raises. No one who has ever gone in to talk about getting a raise has gotten one before the official raise time at the end of the fiscal year. Apparently there's a 3% raise once a year...and that's about it. 

I don't feel like they really look out for the employees here. The higher-ups keep getting raises and promotions, and everyone else is supposed to just sit quietly and drink crappy coffee. 

This kind of turned into a rant, so I really appreciate those who read through it. And thanks in advance for your help.
<bot>: I haven't been at my current company for very long. How do I navigate that question in an interview when/if I'm asked?
