House Republicans are "on their own" as they attempt to pass an emergency response to the southern border crisis, House Minority Leader Nancy Pelosi (D-Calif.) warned Thursday.
"Let me put it this way: The Democrats are not going to enable that bill to pass. That's the number that we're interested in," Pelosi told reporters in the Capitol just hours before the vote. "[Republicans] are going to have to do that on their own."
Democratic leaders have been whipping hard against the Republicans' border bill, largely over concern that language scaling back a 2008 human trafficking law would erode due process protections for the unaccompanied Central American children who have crossed the border in recent months.
A handful of Democrats appear poised to support the GOP bill. Rep. Henry Cuellar (D-Texas), who has sponsored a bill scaling back the 2008 law, said he plans to vote for it.
A number of other conservative-leaning Democrats remain wildcards as the vote approaches. Reps. Mike McIntyre (N.C.), Kurt Schrader (Ore.), John BarrowJohn BarrowDem files Ethics complaint on Benghazi panel Barrow thanks staff in farewell speech The best and the worst of the midterms MORE (Ga.), Jim MathesonJim MathesonWork begins on T infrastructure plan New president, new Congress, new opportunity First black GOP woman in Congress wins reelection MORE (Utah), Kyrsten Sinema (Ariz.) and Ron BarberRon BarberGiffords to lawmakers avoiding town halls: 'Have some courage' Ten House seats Dems hope Trump will tilt House conducts moment of silence for Tucson shooting anniversary MORE (Ariz.) have declined to say how they'll vote.
Blue Dog Rep. Sanford Bishop (D-Ga.) said he's also undecided "but leaning against."
Rep. David Scott (D-Ga.), yet another Blue Dog, said he's "a toss up," but hinted he'd rather support an imperfect bill than leave town without passing something.
"We've got to do something, and we've got to do the best we can do given the situation," Scott said. "There's an urgency here."
GOP leaders ran into trouble Wednesday night, after conservatives in their conference threatened to sink the bill for an absence of language addressing the Deferred Action for Childhood Arrivals (DACA) program.
In response, GOP leaders have scheduled a separate vote on a bill blocking Obama from expanding DACA. It remains unclear, however, if that strategy would appease enough conservatives to pass the underlying border package without Democratic support, as some Republicans are grumbling that the two measures were not combined.
Cuellar said he would vote against the proposal to limit DACA.
Echoing predictions from Rep. Steny Hoyer (Md.), the Democratic whip, Pelosi said the number of Democrats crossing the aisle will prove insignificant.
"I don't think we'll lose too many Democrats," she said.
Thursday's vote is scheduled for roughly 1 p.m.
