In the House, members of the Congressional Hispanic Caucus — who account for 28 of the 194 House Democrats — are expected to decide by the end of this week whether they will vote no against spending bills without an agreement to protect dreamers, according to caucus members and their aides. If they do, aides expect most if not all members of the congressional Black and Asian and Pacific Islander caucuses to join in opposition. Dozens of other Democrats might also vote no — representing more than half of the caucus.
