President Joe Biden will make another trip this Thursday, this time to the California flood front. A new visit that will surely be very scripted. Ten days ago, he had been only three hours in the border town of El Paso, Texas, faced with an influx of migrants from Mexico. To avoid any unforeseen events, the president had not seen the slightest migrant. But, despite this caution, he had acted his age, trudging along the border wall and flanked by two immigration officers.
