U.S. Rep. Doug Collins has become a national political figure after leading GOP opposition to the impeachment of President Donald Trump. But he’s still unsure if that will translate to running for a higher office.

Although Republicans did not have enough votes to thwart that effort, Collins said he and his other colleagues accomplished their goals to paint the process as without merit and led by Democrats who simply dislike Trump.

“We poked so many holes in their theory,” Collins said during an interview with The Atlanta Journal-Constitution on Friday.

Collins said he has received overwhelming support from conservatives, especially those who live in his northeast Georgia district. They applauded his management of the impeachment debate on the House floor Wednesday and how he conducted himself as the top-ranking GOP member on the Judiciary Committee.

Yet, he has not made up his mind about whether he will run as a more conservative alternative to Kelly Loeffler in the 2020 Senate special election.

Loeffler will take office in January after being appointed by Gov. Brian Kemp to replace retiring U.S. Sen. Johnny Isakson. But others, including Trump, had lobbied for Collins to get the job.

When it became clear that Loeffler was the pick, he floated the idea of running against her in November.

However, Collins said his priority was fighting against impeachment and he would decide later about running for Senate. He told the AJC Friday that he has not set a timeline to make that decision.
