A campaign season without crowds

• Louisiana is postponing the state's Democratic primary until the summer.
• Democratic National Committee chairman Tom Perez told Axios' Jonathan Swan in an HBO interview taped March 9 that he has no plans to cancel this summer's convention in Milwaukee. But the DNC is monitoring the situation "every single day."
• Tomorrow's Democratic debate moved from Arizona to CNN's Washington studio with no live audience, and Univision's Jorge Ramos withdrew as a moderator because he may have been exposed to the virus.

The bottom line: Politics is fundamentally about engaging people. This is America's biggest test of what it means to campaign without crowds in the modern age — whether disenfranchisement and lower turnout are inevitable, or virtual interactions can fill the void.
