The results of the Georgia runoff elections show just how much of a liability Trump has become for Republicans

The upset Georgia Senate runoff election victories last week of Democrat Raphael Warnock over Republican Kelly Loeffler and Democrat challenger Jon Ossoff over incumbent Republican David Perdue puts Democrats back in charge of the Senate for the first time since 2014. Julie Norman writes that the victories also highlight the impact of grassroots voter mobilisation efforts by Democrats, while raising questions for Republicans about the electoral limits of aligning with Trump, even before the shadow of the Capitol riot.
