(Reuters) - The future of Democrat President-elect Joe Biden's agenda hinges on two Senate runoff races in Georgia whose outcome might not be known for days after polls close on Tuesday.
Public opinion polls show Republican incumbents Kelly Loeffler and David Perdue have about the same level of support as their Democratic challengers Raphael Warnock and Jon Ossoff.
