This requires an explicit mention.
Democrats are the problem. They don’t care about crime and want illegal immigrants, no matter how bad they may be, to pour into and infest our Country, like MS-13. They can’t win on their terrible policies, so they view them as potential voters!

The use of the word “infest” to talk about people is literally out of the Nazi/anti-Semites’ playbook for talking about the Jewish threat. It was also a standard for talking about Chinese in the western United States and it remains part of the vocabulary for talking about Romani (Gypsies) in parts of Europe. This is the most hard-boiled kind of racist demagogic language, the kind that in other parts of the world has often preceded and signaled the onset of exterminationist violence. The verb “to infest” is one generally used to describe insects or vermin (rats), creatures which are literally exterminated when they become present in a house or building or neighborhood.
