Pennsylvania’s credit rating has been lowered again after a two month budget stalemate that has pitted Democratic Gov. Tom Wolf and the Republican-controlled Senate against the Republican-controlled House of Representatives. The credit rating agency Standard and Poor’s lowered its rating on Pennsylvania’s debt, citing the state’s reliance on one-time cash infusions has put too much stress on its tax collections to pay its bills on time. The downgrade is the second by Standard and Poor’s in three years as state lawmakers struggle to pull Pennsylvania out of a $2 billion budget deficit.
