With just weeks until the midterms, President Trump's declining popularity is becoming a major liability for Republicans. But should GOP candidates distance themselves from the president or stick with him? Republican strategist Liam Donovan explains why breaking with Trump could backfire, particularly for candidates who haven't already established an independent political identity.

On GZERO World, Ian Bremmer speaks with Donovan and Amy Walter, editor-in-chief of the Cook Political Report, about how both parties are approaching the final stretch. Walter explains why Democrats are focusing on the cost of living, the Iran war, and corruption, and how disillusioned Trump voters could determine whether Republicans hold onto their Senate majority.
