GOP pollster John McLaughlin said Sunday that Republicans may be able to fend off Democrats' efforts to take back control of the House in November's midterm elections.

Speaking on AM 970's "The Answer" in New York, McLaughlin told host John Catsimatidis that the key to a Republican victory next month is retaining enthusiasm felt by GOP-leaning voters following the successful confirmation of President Trump Donald John TrumpBiden on Trump's refusal to commit to peaceful transfer of power: 'What country are we in?'

"You’re seeing Republicans in the areas where Trump did well go up in the polls because the Trump voters are reengaged," McLaughlin said.

"If, over the next three weeks, they keep those Trump voters engaged, [then] we have a shot at holding the House, but we’ll definitely pick up some U.S. Senate seats," the pollster continued.

"The Republicans, they need to play offense," McLaughlin said, adding that the party's target should be House Minority Leader Nancy Pelosi Nancy PelosiHoyer: House should vote on COVID-19 aid — with or without a bipartisan deal Ruth Bader Ginsburg lies in repose at Supreme Court McCarthy threatens motion to oust Pelosi if she moves forward with impeachment MORE (D-Calif.), who has battled opposition from within her own party in recent months.

"The person who is the most unpopular national figure is Nancy Pelosi. And the Democrats are hiding her," McLaughlin continued. "The president needs to take her on and expose her because she stands for higher taxes, open borders, fewer jobs. She stands for basically a weaker America."

Democrats are battling for a net gain of 23 seats in the House to retake the lower chamber next month. Republicans hold the advantage in the Senate, where Democrats are seeking to close a two-seat gap.

Republicans trailed Democrats by 13 points on a generic congressional ballot among likely voters in a CNN poll released this week. FiveThirtyEight's election forecast currently gives Democrats a 79 percent chance of winning control of the House next month.
