PITTSBURGH/LATROBE, Pa., Nov 5 (Reuters) - Former President Barack Obama warned about divisions fueling a "dangerous climate" in U.S. politics as he stumped for Democratic candidates on Saturday three days ahead of midterm elections that will determine control of Congress. "This habit we have of demonizing political opponents, of saying crazy stuff, it creates a dangerous climate," Obama said, without referencing Republicans directly. Republicans contend that Democrats have also engaged in political violence, citing the widespread anti-racism protests that rocked the country in 2020. They have criticized Democrats for failing to keep their focus on inflation and crime, two of voters' principal concerns, according to most opinion polls. Scott Flaherty, a 53-year-old mechanic from Pittsburgh who was heading to the Trump rally, said he is tired of Democrats calling Republicans extreme.
