By Robert Yoon, Associated Press WASHINGTON (AP) — Control of the White House and the narrowly divided Senate and House may hang in the balance on Nov. 5, but don’t expect election night to be all nail-biters and barn burners. Chances are some winners will be declared before a single vote has been tallied, just as the polls close in those states. So what gives? Although determining a winner before any votes have been counted may seem counterintuitive, race calls at poll closing time in uncontested or landslide races have been a routine part of election nights for decades, even though competitive, hotly contested races that can take hours, days or even weeks to decide tend to be the most memorable and attract the most attention. The Associated Press will consider multiple factors and analyze available data before determining whether a winner can be declared when polls close in a given state.
