ANALYSIS — We don’t know exactly how many House seats Democrats will gain in November, though Democratic control of the chamber next year looks almost inevitable. But even now it is clear that the midterm results will move Republicans further to the right. Where the Democrats will stand is less clear.

In the House, GOP losses will be disproportionately large in the suburbs and among members of the Republican Main Street Partnership, the House GOP group that puts “country over party” and values “compromise over conflict,” according to its website.

Not all the 70-plus members of the group are pragmatists or generally seek to defuse partisanship, but many are endangered this election cycle.

GOP casualty list?

Reps. Barbara Comstock of Virginia and Mike Coffman of Colorado are headed for defeat, and Democrats are likely to flip the seats of retiring pragmatists such as Florida’s Ileana Ros-Lehtinen, Pennsylvania’s Ryan A. Costello, and New Jersey’s Frank A. LoBiondo and Rodney Frelinghuysen, as well as the seats of former Pennsylvania Reps. Charlie Dent and Patrick Meehan.

Reps. Tom MacArthur of New Jersey, Kevin Yoder of Kansas and Peter Roskam of Illinois are running even or behind their Democratic challengers, as are Mimi Walters of California and Leonard Lance of New Jersey. (Roskam is not listed as a member on the Main Street website.)

Some Republican pragmatists and advocates of increased cooperation with Democrats, including Reps. Will Hurd of Texas and John Katko of New York, are likely to survive the wave. They are the exceptions to the general rule.

But at least 30 of the House members listed on the Main Street website are now at risk in the midterms, and when Rep. Fred Upton of Michigan starts to crawl on to some endangered Republican lists, you know that most of the remaining GOP pragmatists on Capitol Hill have reason to be nervous.

Not every Republican incumbent in a tough race, though, is a pragmatist who at least talks about changing the tone on Capitol Hill.

A handful of Freedom Caucus members are at risk — including Iowa’s Rod Blum, Virginia’s Dave Brat, North Carolina’s Ted Budd and California’s Dana Rohrabacher — and a number of conservatives are retiring or running for governor, including former Rep. Ron DeSantis of Florida (who left Congress last month to focus on his gubernatorial bid) and Steve Pearce of New Mexico.

Rep. Jason Lewis, a Minnesota conservative, will likely lose, and the GOP’s California delegation will take a significant hit.

This isn’t intended to be an exhaustive list of Republican losses, but it does demonstrate that while there will be House losses across the party’s ideological spectrum, the biggest losses — relatively speaking — will be among party members for whom “compromise” is not a dirty word and Donald Trump is a liability.

The House Republican Conference next year will be smaller but also more conservative and presumably more belligerent being in the minority.

Democratic divisions

The effect on the Democrats is more complicated and less certain.

On one hand, Democrats are likely to add a number of more pragmatic members to their caucus. These members won’t be “conservatives,” but they are less likely to see everything in knee-jerk ideological and partisan terms.

Among the likely winners in November are Rep. Conor Lamb of Pennsylvania, who won a special election this cycle and is a solid favorite over GOP incumbent Keith Rothfus in a newly drawn district. Former Navy helicopter pilot and prosecutor Mikie Sherrill looks likely to win Frelinghuysen’s open seat, and state Sen. Jeff Van Drew appears an easy winner in the district LoBiondo is vacating.

If they win, Democrats from upscale suburban areas — e.g., Virginia’s 10th, Kansas’ 2nd and 3rd, Minnesota’s 2nd and 3rd, New Jersey’s 3rd, 7th and 11th, and a handful of California seats — will be well aware of the “swing” nature of their districts, and they will be less likely to be robotic followers of their party’s liberal agenda, particularly on economic issues.

But while the House Democratic Caucus will add more pragmatic members who represent competitive districts, it will also see an influx of progressives who say the party has been too timid when it comes to proposing and defending liberal proposals.

All of the energy on the Democratic side is on the left, and progressives surely will demand an unapologetically confrontational approach to Trump nationally and on Capitol Hill.

The fight over the direction of the party is likely to play out first when House Democrats choose their leadership after the midterms.

In mid-August, NBC News identified more than four dozen Democratic incumbents and candidates who’ve indicated they won’t support Nancy Pelosi for speaker next year if the party takes the House.

Not all of the candidates on that list will win, and Pelosi’s opponents come from both the more moderate and the more progressive wings of the party.

While much of the opposition to Pelosi obviously is generational, not ideological, it’s notable that Lamb, Sherrill, North Carolina’s Dan McCready and Kathy Manning, Virginia’s Abigail Spanberger, Michigan’s Elissa Slotkin and Kansas’ Paul Davis are among those who have said the party needs new leadership.

Republicans will surely call next year’s House Democratic agenda “extreme,” “radical” and “socialist.”

But those labels reflect the GOP’s knee-jerk ideological approach and beliefs as much as the Democrats’ positioning, and the Democratic Party will need to work out its agenda during the next two years, when its voters will pick a presidential standard-bearer.

That nominee will, to a large degree, define the positioning of the Democratic Party just as the 2020 Republican nominee will make a statement about the GOP’s values and direction.
