If Nancy Pelosi links the one trillion dollar Infrastructure Deal to the massive $3.5 trillion budget bill, the Infrastructure bill could lose the current Republican support. If the Infrastructure Bill passes, Democrats can pass the Reconciliation Package without Republican support. So, for Pelosi, it would be a matter of having all House Democrats, Moderates and Progressives, on the same boat. Although both sides support the $1 trillion Infrastructure Deal, the $3.5 trillion spending plan worries Republicans and even some Democrats.
