About one-third of voters gave Collins favorable reviews in the AJC poll while about one-fifth had a negative impression. Nearly half of voters didn’t know or refused to answer.
Still, Collins had a far higher profile with Republicans, possibly due to his ubiquitous presence on cable TV shows defending Trump from impeachment charges. About 53% of Republican voters had a favorable impression of him, compared to just 6% who have negative views.

Among independents, generally a decisive voting bloc in Georgia politics, Collins also has an edge. About 30% of independents have a positive view of Collins, while 16% of those voters feel the same about Loeffler. Roughly 55% of independents don’t know enough about either candidate to form an opinion.
Collins, recently tapped to Trump's impeachment team, is expected to soon decide whether to run. Since there's no primary to hash out nominees, if Collins enters the race he'll be on the same November ballot as Loeffler and several Democrats also in the running.
Matt Lieberman, an educator who is the son of former U.S. Sen. Joe Lieberman, entered the race last year. And former federal prosecutor Ed Tarver recently told the AJC he'll soon join. But they risk being overshadowed by another newcomer who is likely to shake up the contest.

The AJC reported earlier this month that prominent state and national Democrats back the Rev. Raphael Warnock, who is preparing a run for the seat. He gave a preview of his campaign message at the Martin Luther King Jr. Day ceremony this week at Ebenezer Baptist Church, where he is the spiritual leader.
