WASHINGTON, United States — Former Green Party presidential candidate Jill Stein dropped her efforts Saturday to request a vote recount in Pennsylvania, one of three battleground states won by Donald Trump where she is challenging the results. “Petitioners are regular citizens of ordinary means. They cannot afford to post the $1,000,000 bond required by the court,” read a filing submitted in the Commonwealth Court of Pennsylvania. On Twitter, she later added: “#Recount2016 is so expensive because of elected leaders who have refused to invest in a 21st-century voting system.”
