Congress on Thursday approved a $4.6 billion emergency aid package for the southwestern border after Speaker Nancy Pelosi of California capitulated to moderates in her party and withdrew a House amendment with more restrictions and oversight provisions.

But the vote exposed a number of realities about the House majority and its relationship with the Senate.

Here are five political realities that the vote laid bare.

Divisions in the Democratic caucus were on display.

House Democrats have long played up their diversity, saying that the variety of viewpoints strengthen the party’s reach.

But the different factions have frequently clashed, with more moderate members voicing concern that the progressive wing pushes the party too far to the left and more liberal members complaining about the tendency of moderate members to break with the party and vote with Republicans.
