You shouldn't spend money you don't have.

Taking property for the benefit of another, against its owner’s will, is theft.

You should know the difference between your needs and your wants.

Do your duties without overstepping your limitations.

Which leads to:

Compassion at another's expense is not compassion.

The government is not a bank.

Our city/state/country should be attractive to business through freedom, not bribes.

As a U.S. Senator, Daniel Lewis would also follow the Seven Principles of Sound Public Policy from The Mackinac Center For Public Policy:

One
Free people are not equal, and equal people are not free.

Two
What belongs to you, you tend to take care of; what belongs to no one or everyone tends to fall into disrepair.

Three
Sound policy requires that we consider long-run effects and all people, not simply short-run effects and a few people.

Four
If you encourage something, you get more of it; if you discourage something, you get less of it.

Five
Nobody spends somebody else's money as carefully as he spends his own.

Six
Government has nothing to give anybody except what it first takes from somebody, and a government that's big enough to give you everything you want is big enough to take away everything you've got.

Seven
Liberty makes all the difference in the world.
