Quejarse is a verb meaning "to complain," so we translate the above phrase directed at Mexico's voters as:
"And still you're complaining!"

Así que no puedo quejarme.

So I can't complain.

As per our previous discussion of the verb gustar, the phrase above states:

"You wouldn’t like it if they told you who you have to hang out with."

But what does the addition of A ti at the beginning do for the phrase? It simply adds emphasis to the "you," the translation would be same even if it wasn't there.

[Side note: remember we talked about andar's various meanings outside of the obvious "to walk"? The phrase above demonstrates yet another, "to hang out / pal around."]

Él le hizo daño a mucha gente.

He did harm to many people.

-¿Qué daño te hizo a ti, mamá?

-What harm did he do to you, Mom?
