Before getting into the Pandemic and the science topic of today, here is what President Joe Biden will attempt to do tonight in a national address from the U.S. Congress: Initially, the purpose was to prepare the supportive groundwork for his $2.3 trillion jobs and infrastructure spending package .   More recently, this has become a $3 trillion " Build Back Better " program.  A good part of the effort is to gain bi-partisan support by including two items that might draw some Republican interest: Free community college and universal pre-K schooling. The second is that obvious infrastructure focus, for everyone agrees that the nation's roads, bridges, airports and just about everything else, are now deficient.
