Tuesday’s blue wave in the House is set to leave behind a GOP conference that is far more conservative — and more loyal to President Trump Donald John TrumpBiden on Trump's refusal to commit to peaceful transfer of power: 'What country are we in?'

A large chunk of centrist Republicans were either wiped out at the polls on Tuesday or are planning to retire at the end of this Congress, while the ultra-conservative House Freedom Caucus is actually expected to expand its ranks next year.

That means that when Republicans assume their new role in the minority, the GOP will largely be unified as they rally against the Democratic agenda and defend Trump from an onslaught of investigations and hearings.

Now, Graham is one of Trump’s top allies on Capitol Hill.

“You’re going to see the Graham effect,” the aide predicted.

“The Republican herd has been culled. And the culling was the more moderate members,” said the GOP aide. “The center of gravity in the conference has moved to the right.”

Meanwhile, a new crop of conservatives won election, including Chip Roy, whom Politico once described as the “next Sen.

The Freedom Caucus, a band of roughly 30 hard-liners, lost two of its members Tuesday, but is still expecting to net upwards of five members in the new Congress.

And with a slimmer caucus, that means the group — which has torpedoed GOP-backed bills to get what they want — will make up a larger percentage of the overall conference.

But, as a source close to the caucus pointed out, all Republicans will end up using similar obstructionist tactics once they are no longer in power.

“Everybody acts like the Freedom Caucus when you’re in the minority,” the source said.

Several Capitol Hill sources predicted that the GOP conference, where infighting between competing factions has spilled into public view for years, would band together against the Democrats’ priorities. And some of the ideas supported by the left will give Republicans plenty to dislike, from Medicare for All to a $15 minimum wage.

The biggest points of contention among House Republicans have stemmed from when they have actually tried to put pen to paper on certain issues, such as repealing and replacing ObamaCare — something the GOP campaigned on for years. The health-care debate illustrated that it’s far easier to be against an idea than come up with actual policy solutions that everyone can agree on.

“Republicans were more united when they were on defense then when they were on offense,” said Rep. Warren Davidson Warren Earl DavidsonGOP-Trump fractures on masks open up House punts on FISA, votes to begin negotiations with Senate House cancels planned Thursday vote on FISA MORE (R-Ohio), a member of the Freedom Caucus, referring to the last time the GOP was in the minority. “That’s just the challenge of offense. I’m sure Democrats will deal with that.”

But a more conservative GOP caucus may be more inclined to throw bombs than cut deals, not making life any easier for the Democrats who hope to notch some bipartisan legislative wins ahead of 2020.

Davidson, however, noted that some Republicans may be willing to work across the aisle on certain issues, especially if Trump is leading the push.

“There may be coalitions where some Republicans will work with Democrats,” Davidson said. “But it’s issue by issue.”

Democrats are itching to use their new subpoena powers to investigate the Trump administration, including scrutinizing the recent ouster of Attorney General Jeff Sessions Jefferson (Jeff) Beauregard SessionsGOP set to release controversial Biden report Trump's policies on refugees are as simple as ABCs Ocasio-Cortez, Velázquez call for convention to decide Puerto Rico status MORE and getting their hands on Trump’s tax returns and bank records.

“That will unite a lot of people in opposition to their actions, if that’s the play call,” Davidson said.

Democrats will also be under immense pressure from the liberal base to launch impeachment proceedings against Trump, though party leaders have kept the idea at arm’s length.

Still, if Democrats are seen as overstepping their bounds with their newfound subpoena powers, some Capitol Hill sources predicted that Republicans — even those who have not publicly embraced the president very tightly — may unite in their defense of Trump.

“Democrats are going to jump the shark. Everyone knows that they’re gonna go overboard,” the aide to the conservative lawmaker said. If so, the aide said it may surprise the public to see which lawmakers come out to back the president.

And with the loss of so many outspoken moderates, there will be less voices in the party willing to challenge the president.

Trump, who has repeatedly attacked lawmakers who challenge him, seemed to relish in the fact that some of his Republican critics lost their reelection bids.

“You had some that decided to, let’s stay away, let’s stay away. They did very poorly,” Trump said at a press conference at the White House. “I’m not sure that I should be happy or sad, but I feel just fine about it.”
