Party officials say there is zero concern of being short on votes, with nowhere near 18 Democrats expected to buck their party on the House floor. Senior Democrats say privately they hope to contain their losses to under double digits, and are so far on track to do so, according to multiple lawmakers and aides.

Even if some moderate Democrats decided to split their vote on the two articles of impeachment, Pelosi and her leadership team would have plenty of room. Democrats — who have 233 members in their caucus — are also expecting support from the one independent on impeachment. There are also four vacancies.

But vote-counting is likely to be a guessing game until it reaches the floor itself, with few Democrats seeing any incentive to preview their position.

Speaker Nancy Pelosi has told members there will be no attempt by the whip team to sway them ahead of the vote, saying at a Wall Street Journal event on Monday, “I haven’t counted votes, nor will I.” But by next Wednesday, Pelosi and her team will know the precise number of Democrats who will vote against removing Trump from office.

Democratic leaders, however, are most concerned about a group of five to seven members in heavily pro-Trump districts.

Two are all but certain to oppose Trump’s impeachment : Reps. Collin Peterson of Minnesota and Jeff Van Drew of New Jersey. Both lawmakers voted against the resolution formally initiating the impeachment inquiry, and both have shown no signs of changing their views.

Several other moderates are also on the radar, including Reps. Anthony Brindisi of New York, Jared Golden of Maine and Kendra Horn of Oklahoma — whose districts all went for Trump by 10 points or more in 2016.

“I’m still reviewing,” Horn told reporters on Wednesday.

Brindisi, Golden and Horn are among the 31 House Democrats in pro-Trump districts, including 22 freshmen, who have felt the most intense anxiety within the caucus over this year’s impeachment drive.

From the start, these members have been concerned with how exactly the caucus should move ahead with impeachment, what the message should be, and the best tactics to counter Republican attacks.

Several other Democrats in heavily pro-Trump districts — Reps. Joe Cunningham of South Carolina, Max Rose of New York, Xochitl Torres Small of New Mexico and Ben McAdams of Utah — have also yet to disclose how they’ll vote.

“This is not something that we’re going to operate on anyone’s timeline,” Rose said about his decision-making process, noting that he’s talking constantly to advisers, friends and experts while reviewing the transcripts.

“I take the speaker at her word that this is a vote of conscience, as is every vote here,” Rose said about whether he was facing pressure from Democratic leaders.

Some undecided Democrats have been seeking the counsel of their caucus leaders, including Pelosi, as well as senior members who endured the last impeachment process. But most lawmakers are making the determination privately, reading over their caucus’s articles of impeachment in between committee markups with conversations just among their closest colleagues.

“What I’m doing over the next couple of days, I’m going back, reviewing the testimony and reviewing the transcripts, the documents that were collected during the inquiry the last few months,” said Rep. Jason Crow of Colorado, who is also undecided. “I’m giving a very robust look at the full body of evidence collected during the inquiry, and I’ll decide during the next few days.”

Crow, an Army veteran who is among the influential group of national security freshmen, said he has consulted privately with the House Intelligence Committee chairman, Rep. Adam Schiff (D-Calif.), as he makes his decision, calling him “somewhat of a mentor and a friend of mine since coming to Congress earlier this year.”

“I’ve been in touch with him during the process,” he added.

Many say they are waiting to see the final version of the articles, after the Judiciary Committee completes its two-day markup, though the panel is expected to make few changes, if at all.

“As soon as they’re formally adopted, I’ll make a decision,” said Rep. Josh Gottheimer of New Jersey, a second-term moderate in a purple district, referring to the Judiciary markup.

In the Capitol, some vulnerable Democrats have struggled with how to navigate the national impeachment furor, at times flatly ignoring reporters’ questions on the subject or blatantly trying to change the subject.

Some have begun going public with their decisions, though, often speaking to local news outlets with a lengthy explanation of their rationale, like Reps. Susan Wild of Pennsylvania and Sharice Davids of Kansas.

“I’ve got a tough district, it’s a purple district. I heard from constituents on both sides constantly. I weighed all of that, but ultimately, it came down to a question of law and order,” said Wild, who spent more than three decades as a lawyer.

Several of these moderates, like Slotkin, have been among the most vocal in trying to shape the caucus’s path, like the “gang of nine” freshmen with national security backgrounds who held conference calls with Pelosi.

A small group of vulnerable Democrats even met this week to quietly discuss a potential censure resolution instead of impeachment as an attempt to draw bipartisan support. But the idea was quickly swatted down by leadership and other members of the caucus.

“It’s not being seriously discussed in the Democratic Caucus in the House,” said Rep. Tom Malinowski of New Jersey, a freshman frontliner who sits on one of the panels investigating Trump.

Pelosi and her leadership team have worked hard to stamp out many of those worries, announcing this week that Democrats would draft two narrowly focused impeachment articles related to the president’s pressure campaign to solicit help from Ukraine.

But the biggest fear is that impeachment will drown out the caucus’s legislative successes this year. To help bolster her moderates’ case, Pelosi hand-delivered the gift of several high-profile legislative votes in the final two weeks ahead of the vote to oust Trump.

Democrats are slated to vote on a trade deal that’s much needed in farm states, a sweeping drug pricing proposal and a Pentagon policy bill that turned into a grab bag for freshmen — all before Christmas.

Democratic campaign strategists, meanwhile, insist they are on solid footing, with most polls showing, at best, a slight majority favoring impeachment and, at worst, opinion nearly split.

They also point out that roughly half of voters said a candidate’s position on impeachment would not influence their vote choice, while only about a quarter on either side said it would make them more or less likely to support a candidate.

Battleground Democrats, meanwhile, will also get some long-awaited reinforcement back home with a $10 million cash infusion to help promote their agenda from Michael Bloomberg, the billionaire former New York mayor running for president — fighting back against an ever-escalating onslaught of GOP attack ads.

“I’m keeping an open mind, reading through the articles and talking to my constituents,” Rep. Haley Stevens of Michigan said. “But one thing is very clear — and this is how I felt when I voted for the inquiry — is that we can’t be divided on the rule of law. This is obviously a painful moment.”
