With Trump's backing, Walker freezes Senate GOP field in Georgia

Warnock, who is running for a full six-year term next year after narrowly winning his seat in a special election in January, is a top target for Republicans. And with the backing of Trump and his closest allies, who believe that Walker is uniquely able to unite a party torn apart by their 2020 losses, prospective Republican candidates are signaling they are willing to sit out until the legendary athlete makes a decision. But the prospect that Walker could have the field to himself is causing anxiety among some Republicans in Georgia and Washington, who privately are uncertain whether the first-time candidate and Texas resident could handle the enormous challenges ahead. And they're worried that Trump is propping up a candidate simply because he has been a loyal friend, rather than assessing the former NFL running back's electoral viability in a pivotal battleground that could again determine the next Senate majority.
