The election was a triumph for the LV, which was by far the largest party in the region with 35.2% of the vote, up from 14.7% of five years before, and got 20 seats in the Regional Council, up from 11.

("Io non ho nulla contro i gay, ma la possibilità dell’adozione mi pare un’estremizzazione dagli effetti imprevedibili").
In August 2010, an anti-globalization group pickets in Vivaro against the GMO plantations. The manifestation was supported by Zaia, that claimed a "return to legality", despite his predecessor Giancarlo Galan, member of his coalition, was pro-GMO.
After a flood in 2010, Zaia and his coalition changed a regional law to permit the reconstruction of rural ruins until 800 cubic meter. The Democratic Party claimed this as a "cementification" attempt. Also the National Association of Building Constructors ("Associazione nazionale costruttori edili", ANCE) called the law a "bad choice".
He was criticized when, after the flood, he asked for more funds for the reconstruction, and said: "It's a shame spending 250,000,000 € for four stones in Pompei."
In March 2014, Zaia supported a plebiscite on the Venetian independence. Zaia has compared status of the Veneto within Italy as that of Crimea within Ukraine, which voted to secede from Ukraine following a plebiscite.
