I think it's important that when we're running for the highest office in the land, that we recognize that we're living in dangerous times and we have to be serious about it, that our words have consequences.

You shouldn't cut and run.

There's no such thing as being too nice. Nice being nice doesn't mean you're not strong that you don't have fortitude.
