(NewsNation) — During a rally in Dayton, Ohio, former President Donald Trump teased a “big announcement” coming the week after the midterms.

“I’m going to be making a very big announcement on Tuesday November 15 at Mar-a-Lago in Palm Beach, Florida,” the former president said.

Previous reports indicated he could announce a 2024 run for president some time that week.

“We want nothing to detract from the importance of tomorrow,” Trump said Monday night.

Republican momentum has surged in the weeks leading up to the Nov. 8 midterm elections. The GOP is now favored to gain control of both chambers of Congress from Democrats, according to Decision Desk HQ.

Trump was in Dayton to rally support for Senate candidate J.D. Vance and other Republican statewide candidates, such as Gov. Mike DeWine.

The former president has frequently hinted at a 2024 run, often saying in speeches he would “probably have to” run again.

His spot in a 2024 Republican primary field would be imposing, though perhaps not a total deterrent to would-be challengers. Florida Gov. Ron DeSantis, Trump’s vice president, Mike Pence, former Secretary of State Mike Pompeo and former New Jersey Gov. Chris Christie have also signaled their interest in running.

In a late-July NewsNation Decision Desk HQ poll, nearly 57% of respondents said Trump should not run in 2024. They were then asked which candidate they would prefer, but in a field that included DeSantis, “Someone else” received the most votes with 38%.

In that same poll, registered voters also rejected Biden’s run for a second term. Sixty percent of people said he should not run again. Just like with Republicans, no alternative Democrat received a majority of support, with “someone else” garnering 44% of the vote.
