The URNG has an unofficial count of the distribution of congressional seats posted on its Facebook page.
Viva-EG looks like it might have done well (led by Caballeros for the presidency and Nineth Montenegro for congress. Controversy might even have hurt them.
And three seats for the Frente Amplio is a bit of a push. When I spoke with some URNG last year, holding on to their two seats was critical and capturing four or five would have been a coup. Unfortunately, that was before its alliance with Winaq and the ANN so three was probably the minimum they were looking for.
Again, unofficial but probably not too far off the final results.
