Lisa Desjardins:

This is an enormous and enormously important discussion.

But, first, let’s just get our hands around what exactly lawmakers are talking about. Simple version? Four big things are on the table here.

One, classic infrastructure, you know, fixing roads, bridges, rails, public buses, with one idea added, broadband Internet expansion. Second, clean water. That includes work to replace lead pipes. Third, another big one, climate change and energy.

That means things like manufacturing. Democrats want tax credits to lower carbon output, and things like a better, greener power grid. One headline item? Electric vehicles. President Biden wants rebates to encourage buying electric cars, and funding to build more charging stations. Some Democrats say that is a must-have.
