Biden has kept progressives mostly happy during the first six months of his presidency. But the infrastructure plan poses a significant test for that relationship. "We cannot afford a president and an administration that trades progress and policies that will make people's lives better for the hope of bipartisanship when there is no track record, no history to suggest that is possible," said Mary Creasman, the chief executive of the California League of Conservation Voters, who said the bipartisan bill doesn't do enough to address climate change. "Our biggest danger is we may not have the leadership that is willing to do the hard thing and say, 'Look, sometimes as a leader, I don’t get to make everybody happy,'" Creasman said.
