In the run-up of the 2018 provincial election, the autonomist centre-left broke up, as both the PD and the UpT were no longer willing to support Rossi as candidate for president. The PATT thus ran as a stand-alone list, in support of Rossi. Maurizio Fugatti of the LNT was elected president with 46.7% of the vote and the LNT was the largest party with 26.7%, while the centre-left's candidate and the PD stopped at 25.4% and 13.9%, respectively. For his part, Rossi won 12.4%, while the PATT was reduced to 12.6% and four councillors (including Rossi). Kaswalder's AP and Ottobre's Dynamic Autonomy won 3.0% and 2.0%, respectively.
