Part of the problem I have is the arrogance he displayed. Seriously, calling Elliot an idiot for asking a simple question? I also find it interesting that she's making that kind of money and he makes less. I wonder what duties she has.
Nepotism, as pointed out, is not illegal. When an elected official makes an ass of himself as Andy did tonight, he reveals the reason most people are against it. That being said, he owns Madison and Venice to a large extent. Those people will never oust him.
