As part of building a broader coalition ahead of the 2007 elections, ARI's leader Elisa Carrió, reached out to centrist figures such as Patricia Bullrich and María Eugenia Estenssoro.

In May 2008, the block, led by Eduardo Macaluse, announced that they were forming a new party, Solidarity and Equality (Solidaridad e Igualdad Sí).

In early 2009, Argentine politics was seeing rising tensions, with defections from the ruling Front for Victory block and fierce debate over the President's proposal to move legislative elections forward by several months.

However, in a surprise move, Martínez and his colleague María Rosa Díaz announced in March 2009 that they would be supporting the Government and completely leaving ARI.

They would nevertheless continue to support Fabiana Ríos, the ARI governor of Tierra del Fuego.
