Tereza Cristina Is Not Running for the Senate. She Is Splitting the Right.

BRASILIA — Sen. Tereza Cristina (PP-MS) is building support outside Jair Bolsonaro’s political base to challenge Senate President Davi Alcolumbre (União Brasil-AP) in the Feb. 1, 2027 vote, even though the opposition already has a candidate: Sen. Rogério Marinho (PL-RN), the name the Liberal Party put forward and the one the Bolsonaro base recognizes as the real opposition.

Two challengers, one incumbent and a secret ballot. Every senator Tereza Cristina wins outside the right is a vote Rogério Marinho does not get, and the only name that gains from that arithmetic is Alcolumbre’s.

Cristina, a former agriculture minister under Bolsonaro, says her candidacy is definitive and personal. “My project has always been the Senate: to be the first woman to hold this chair in 203 years,” she said. She counts on the backing of female senators and of Sen. Damares Alves (Republicanos-DF), and she has made a set of promises aimed at the right: support for impeachment proceedings against Supreme Court justices, a constitutional amendment setting term limits for the court, a higher minimum age for justices, who can now be appointed at 35, and changes to the Senate’s internal rules to reduce presidential powers. She has also spoken of a “freio de arrumação,” a brake to tidy up the Supreme Court, which is a softer promise than the one Marinho has made.

Who is who

Both senators served in the Bolsonaro cabinet and have worked together, though they clashed over the 2024 municipal race in Campo Grande. They agreed that whichever of the two shows the stronger chances against Alcolumbre will carry the opposition’s candidacy. In practice, Marinho is the one carrying the cost of confronting Alcolumbre head on, without asking permission from the Centrão, the bloc of centrist parties that decides most Senate votes. Cristina is the one reaching for what she describes as senators outside the bolsonarista bubble, and her dialogue with centrist parties and with allies of the Lula regime is closer than Marinho’s. Those are the sectors that have long preferred Alcolumbre.

Why it matters

The Senate president decides whether impeachment requests against Supreme Court justices ever reach a vote, and critics on the right accuse Alcolumbre of sitting on them. We have followed Marinho’s pledge not to do the same and the pattern of appointments that keeps tilting the courts toward the Lula regime. For American readers, the chair is the point where the Brazilian Congress either checks a court accused of persecuting dissidents or does not, under a government whose 2022 victory millions of Brazilians still dispute.

The argument

The vote is secret. A majority of the 81 senators is needed, and each one Cristina wins outside the right’s core is a vote that does not go to Marinho and, in practice, helps keep Alcolumbre in command. The agreement that only the stronger candidate proceeds sounds reasonable in a speech. In practice it already splits the field months before February. The right does not need a third way. It needs unity behind the candidate who will confront the status quo, and anything else works as dilution.

The record

Confirmed: the vote is set for Feb. 1, 2027; Cristina and Marinho are both running against Alcolumbre; Cristina has made the pledges listed above and described her candidacy as definitive; the two agreed that the stronger of them carries the opposition. Argued, not established: that her outreach will cost Marinho votes or help Alcolumbre keep the chair. That depends on a secret ballot no one can see, and Cristina presents her campaign as a way to widen the opposition’s reach.

What the record shows is a challenger spending her time with the senators who have kept Alcolumbre in place, while the candidate who chose the direct fight is left to carry it. If the opposition enters February with two names, the chair stays where it is, and the rest is theater.
