President Donald Trump has yet to endorse a candidate in Georgia's Republican primary. Some Republicans are worried that a three-candidate field will make it harder to beat incumbent Sen. Jon Ossoff. He has raised more than any other U.S. candidate, far outpacing his opponents. He is also making his case to voters while the Republicans compete with each other. All three have touted their support for Trump. Strategists believe Trump is remaining cautious to avoid endorsing someone who loses. The Texas Republican primary is primed for a bitter and expensive runoff after Trump declined to endorse anyone, but he said he would make his pick soon.
