If my house should be on fire, I don’t much like the idea of paying the person who started the fire to help me put it out, especially if he was planning to put it out with gas.

Kamala says she would fix things, you know the border, the economy, the wars, the crime. It was she who helped to cause the problems. And by the way, her way of fixing it is to pour more gas on it. (figuratively, for those who cannot figure it out)
