Will the right win the Senate? Polls say that Vox's withdrawal is key

The joint list of PSOE and Frente Amplio has impacted the Senate majority of PP and Vox. Vox is considering not running in several provinces to avoid splitting the conservative vote. If they withdraw from 13 to 19 territories, the chances of PP and Vox achieving a majority increase significantly. The electoral system favors the leading party in each province, complicating the dynamics for smaller parties. Current simulations suggest that without Vox's participation, the left could gain more seats, reducing the likelihood of a PP-Vox majority. The final decision by Vox will be crucial for the Senate's control.
