I saw one of these shirts in the wild and it bummed me out a little. Seems like a tasteless slogan to get going, and... just oddly pro-authority sounding. I expected Harris to dissapoint me eventually (Obama 2.0) but I thought she'd at least give me until after the election.
I expect she'll probably have to use that phrase again in the upcoming debate with Trump. What with the way he tends to ramble like a doddering old man who gets angry when people don't listen to the weird shit that comes out of his mouth.
