House Republicans believe they are gaining momentum after a terrible week for Democrats and a strong one for President Trump.

GOP lawmakers are becoming optimistic they have a chance to pick up seats or even win back the majority in November.

Taking back the House would require picking up at least 18 seats and would be a tough climb, but Republicans say the turmoil in the Democratic Party and a strong economy bolstering Trump give them reasons for optimism.

Spirits were running high during the House Republican Conference meeting Wednesday morning — on the heels of Monday’s disastrous Iowa Democratic caucuses and Tuesday night’s State of the Union address and just ahead of Trump’s impeachment acquittal in the Senate — with some members saying they feel better positioned than they have in recent months.

A senior GOP aide who attended the meeting said Rep. Roger Williams (R-Texas) told colleagues, “Let's do what we've been doing, stay on message and we'll get the majority back.”

Republicans felt even more rejuvenated following Trump’s remarks at the White House on Thursday celebrating his acquittal, when he gave enthusiastic shoutouts to his congressional allies such as House Minority Leader Kevin McCarthy (R-Calif.) and vowed to help them win back the House.

“I will say that you're going to be Speaker of the House because of this impeachment hoax. I really believe it,” Trump said to McCarthy. “And I'm going to work hard on it. I'm going to try and get out to those Trump areas that we won by a lot. And you know, in ‘18 we didn’t win.”

“We are going to win a lot of seats,” he added. 

McCarthy later said that between the strength of the economy and impeachment polling poorly in battleground districts, he feels good about the GOP’s odds for November.

“Look at our favorability rating — it's the best it's been since 2004, 2005. Look at the successes we've had. And then when you contrast that to the Democrats, what do they have?” he said Thursday before taking a swipe at House Intelligence Committee Chairman Adam Schiff (D-Calif.) and Speaker Nancy Pelosi (D-Calif.).

“You've got the freshman members in Trump districts very upset that Schiff and Pelosi put them in this place,” he added.

Republicans are also looking to capitalize on Pelosi’s tearing up of Trump’s speech after his third State of the Union address on Tuesday, something they hope to hammer home with swing voters.

“There could be no sharper contrast between the president's State of the Union, talking about the great comeback of America because of the things that he's done to get our economy back on track and rebuild our military, contrasted to the complete and utter incompetence upon Democrats to be able to conduct a caucus in Iowa or to conduct themselves with basic decorum on the House floor during the State of the Union,” House Minority Whip Steve Scalise (R-La.) told The Hill.

“I think it's a sharp contrast, and America is watching. And they realize these are not the people that can be trusted with the reins of government when you've got a president who's been delivering for families and has real results that benefit hardworking Americans,” Scalise added.

And while the election is still about nine months away, GOP lawmakers said they expect campaigns and outside groups will highlight Pelosi’s actions and the fumbles in Iowa between now and then.

“I'm sure there are going to be some campaigns and organizations that probably put enough money behind an ad making sure it doesn't get out of the attention of the voter because it was so different than what we ever expected in the past,” Rep. Rodney Davis (R-Ill.) told The Hill.

The GOP’s wins this week may have provided a confidence boost, but Rep. Greg Walden (R-Ore.), who served as chairman of the House Republicans’ campaign arm during the 113th and 114th Congresses, said it’s still too early to tell what issues will resonate with voters in the fall.
