We got a quarter inch of snow last night. Not enough to warrant shoveling, but enough to make the albedo high, reflecting ~90% of incident sun light. And it is partly sunny this morning, so a quick, lazy science experiment: if I sweep a strip revealing the blacktop (< 10%), will the sun do the rest?

There’s 5 color-coded checkboxes for too many races to fit in a single screenshot. Conspicuously missing? A checkbox for Republicans. Their best showing is “runoff.” In Texas. Yet the @apnews.com headline depicts yesterday’s election results as a “quiet rebuke” for Trump.
