Former Speaker Newt Gingrich (R-Ga.) is the top contender in a new poll to be presumptive GOP presidential nominee Donald Trump’s running mate.

On Tuesday morning, Gingrich had 39.3 percent support in a Drudge Report poll that asks users whom Trump should pick to run on his ticket.

{mosads}Sen. Joni Ernst (R-Iowa) was in second place, with 31.3 percent of the vote.

Other contenders include Sen. Jeff Sessions (R-Ala.), with 15.2 percent, and Indiana Gov. Mike Pence, with 7.4 percent. New Jersey Gov. Chris Christie takes 5.4 percent and Sen. Bob Corker (R-Tenn.) has 1.5 percent of the vote.

The Drudge Report online poll surveyed 112,155 people as of about 10:30 a.m. on Tuesday.

Gingrich has been floated as a potential running mate for the presumptive GOP nominee and news surfaced last month that he was reportedly on Trump’s shortlist.

Trump has also fueled speculation recently about Pence, after meeting with the Indiana governor this past weekend. Trump also praised Ernst after spending time with her. He said she has “done a fantastic job for the people of Iowa and the U.S.”

Trump said previously he plans to announce his running mate at the Republican National Convention later this month. But his team is reportedly considering acting more quickly and could reveal the decision earlier.
