I was reading today that even a "red ripple" (losing less seats than in the past) could still be disastrous because the margins of majority are much slimmer. edit to add link below. I bolded the part I was referencing.
Democrats across the country scrambled Thursday to bolster candidates in places President Biden carried safely in 2020, the latest sign of panic that they could face major losses in next week’s midterm elections.
Vice President Harris and former secretary of state Hillary Clinton held a joint rally in an effort to rescue New York Gov. Kathy Hochul (D), who faces a close race in a state Republicans haven’t won in two decades. Biden traveled to New Mexico and Southern California to support vulnerable Democratic incumbents — bypassing Arizona and Nevada, where officials fear he could be a drag on senators in tight races. Biden and Harris plan to spend part of the weekend in Illinois, boosting House candidates in suburban districts that have been trending back toward Republicans since 2020.
As Republicans have focused on inflation and crime to go on offense in Democratic territory over the past month — competing in traditionally blue districts in California, Oregon, New York, Illinois and elsewhere — there’s a growing sense among Democrats that there’s little they can do at this point to combat the combined forces of history and economics.
“There’s a general malaise that’s hanging over the country,” said Joel Payne, a Democratic strategist. “What you’re seeing is an angry electorate that keeps kicking the people in charge out. They did it in 2016. They did it in 2018. They did it in 2020. And, if things hold to what it’s looking like, they’re probably going to do it again in 2022.”
While many Democrats have privately believed for months that Republicans were likely to take the House, they have expressed increasing fears in recent days that voters could hand the GOP a significant majority — an outcome that would amount to a major rebuke of the party in power. In some cases, the party appears to be conceding seats it previously competed for, a retrenchment that strategists worry could signal a “red wave” of widespread Republican victories on traditionally Democratic turf.
While the battle for control of the Senate remains closely contested — with both parties pouring millions of dollars into a handful of states that will determine whether Democrats maintain, or even add to, their slim majority — in the House the debate has shifted to predicting how large the new Republican majority will be. Democrats have 220 seats in the House now, and need 218 to maintain control.
One House Democratic strategist said that if Democrats hold 200 to 205 seats, they will consider it a good night. If the party ends up with 190 seats or less — a loss of 30 seats that would require several districts Biden carried by double-digits to flip — that would reflect a big red wave, said the strategist, who spoke on the condition of anonymity to discuss internal deliberations.
Biden allies are preparing to spin even a defeat as a win for the president, since President Barack Obama lost 63 seats in 2010 and President Donald Trump lost 40 in 2018, and Biden is not expected lose as many. But because Biden began his presidency with a much smaller majority than his predecessors, even modest losses could leave Democrats with fewer seats than the 193 they had in 2011.
The party has continued to express confidence about holding the Senate, where elections are historically less dependent on the national political environment than House races. Still, a number of competitive contests have tightened in recent days as Republican candidates have continuously linked their opponents to Biden, who faces stubbornly low approval ratings.
