Surprisingly (to me, anyway), the congressional delegations of three of Colombia’s mainstream political parties have lined up in support of the left government of President-Elect Gustavo Petro.

By my best count—which could be off by a bit, and is subject to constant change—Gustavo Petro’s pro-government coalition now includes 78 of 108 senators, and 135 of 188 House members. Here, I added yellow highlights to graphics created by El Tiempo to show, as best as I can approximate, what the incoming President’s majorities look like:

The Liberal Party, led by former president César Gaviria, announced its support for the incoming government on June 22, joining the Green Party, Petro’s Pacto Histórico, Comunes (the former FARC), at least 9 of the 16 legislators representing special temporary districts for victims, a result of the peace accord, and some smaller parties.

On June 25, 14 senators and 25 House members from the Conservative Party signed a declaration reading, “We will not be an opposition party, and we declare our support for the legislative agenda that the incoming government proposes.”

On June 26, the “La U” party—which backed every sitting government since its creation in 2005—declared its decision “to be part of the government’s parliamentary coalition.”

Cambio Radical, another traditional center-right party, has yet to declare that it will back Petro’s government, but it has not closed the door.

The only large party now clearly in opposition to Petro’s incoming government is the far-right Centro Democrático of ex-president Álvaro Uribe and outgoing President Iván Duque. Petro and Uribe are likely to meet this week.
