(CNN Spanish) -- Colombia entered the final stretch of the race for the regional elections in which mayors, governors, councilors and departmental deputies will be elected. A midterm election that is a kind of referendum on the management of both elected officials in the 2022 general election, and that in turn can shape a new political landscape in the country.

One of the most followed contests in these elections are those of the mayors of the main cities of the country. Recent polls have pointed to candidates emerging as potential winners, although, as they always say in Colombia, the "big poll" to measure the power of political parties is on election day, this time, October 29.

This is the pulse for the mayors of the main cities, according to the most recent surveys published between August and September, from pollsters endorsed by the National Electoral Council of Colombia:

• This is the card of the candidates for Mayor of Bogotá

Polls on the Mayor's Office of Bogotá

It is perhaps one of the most important positions to be disputed this October 29, because it is the mayor of the capital of Colombia. This race is disputed by nine candidates of different ideologies who seek to succeed Mayor Claudia López, the first woman popularly elected to this position in 2019 and who ends her term on December 31, 2023.

In several polls published between the end of August and the beginning of September, the candidate of the New Liberalism, Carlos Fernando Galán (center-right), points as the favorite to be the next mayor of Bogotá. He is followed by Gustavo Bolívar, of the Pacto Histórico Bogotá movement (left) and Juan Daniel Oviedo of the Con toda por Bogotá movement (center-right).

The rest of the candidates have a voting intention of less than 10%, so, if these figures are confirmed in the ones, they would be out of competition for a second round, which would only take place in Bogotá from this year's elections. An eventual runoff is possible if a candidate does not get 40% of the vote and a 10% lead over his immediate competitor. The first two with the most votes go to the second round.
