Yes, in Pacifico only 2 names with 1 point
In Mexico, on first seasons they nominate (a lot of times) with 2 and 1.
Only in the first main season they voted with 2 and 1 in all the rounds. In season 2 and VIP 2, they voted with 2 and 1 only in a few rounds, and in all the other seasons they voted in a different way each round (in VIP1 they voted with 3, 2 and 1)
But maybe the producers decide to change the nominations rules after a few weeks like in the first season. In the first season, during the first weeks (I'm not sure if it was only the first one), they voted like in almost all the countries, but then they changed the rules to make it more like "Protagonistas"
