If Trump were to tweet what you just posted we would never hear the end of it. Trump knows demographics as well as the left and is working most likely a delay plan in my opinion. There is one catch, prosperity. White people are also waking up to the reality of demographics - and and may be starting to have more children because for the first time in their lives they may understand that they also matter.
I would not advocate DJT tweeting as such. And prosperity doesn’t save us from the abyss of entitlement. We built Venezuela’s oil-based economy into an economic powerhouse. Now look at it. Hispanics think from emotion. That doesn’t mean they can’t learn and apply logic. It just isn’t in their culture.
