Grover Norquist Does Not Make Sense

I just don't understand how this guy became so prominent in the GOP establishment that people were scared of him when he says things like this.

"When you got married did your wife understand there was an expiration date on that promise? When you borrowed money to buy your house did you say, 'Oh geez. That mortgage? That was 10 years ago. You're still asking me for money?' You make a commitment, you make a commitment," says Norquist.

Did he just compare not hiking taxes to a marriage? Also that mortgage comment doesn't make sense when circumstances change. For instance a person would be a fool to keep the same mortgage as they had 10 years ago if it was possible to refinance it. If economic conditions change then you have to change with them. If taxes need to be hiked then just do it so it doesn't effect the vast majority of Americans. It is better than building up trillions more in debt.
