Why do Trump and Vance double and triple down on their racist inventions that Haitian people are eating pets. The answer is simple enough. It commands media attention. Racism and xenophobia are at the core of their beliefs. And it is also at the heart of their voter mobilization strategy.
In most campaigns, voter mobilization combines activating the base with persuading the undecided. In Trump’s campaign the accent is heavily on the former. And accomplished by embracing the worst forms of racism, xenophobia, and misogyny.
How low will Trump and Vance go? As low as necessary. In other words, whatever it takes to mobilize their base on election day is in play. No lie is too big or too small. We would be naive to expect anything different.
