Republicans will eventually fall in line if kemp wins.If Kemp wins the primary he’s going to be completely gimped in the general election. I think Kemp can beat Perdue, who was proven to be corrupt and a terrible campaigner. If that happens there will be tens of thousands of radical republicans who will simply refuse to vote for Kemp against Abrams and likely doom him.
Therefore it seems like the dem strategy should be to blast Perdue and focus on hurting him.
