Experts warn of red or blue "mirage" in early election night results

Voting experts are warning people to be aware of a red or blue mirage in early results as they could be misleading than the final outcome. According to a top Democratic data and analytics firm, Hawkfish, President Trump would see an early lead in some key battleground states, but it will slowly narrow as more mail-in ballots are counted. The agency's CEO, Josh Mendelsohn, calls it a "red mirage" and joins CBSN to discuss what states could experience such a scenario.
