Wis. Stat. § 5.10: Presidential electors.

Although the names of the electors do not appear on the ballot and no reference is made to them, a vote for the president and vice president named on the ballot is a vote for the electors of the candidates for whom an elector’s vote is cast. Under chs. 5 to 12, all references to the presidential election, the casting of votes and the canvassing of votes for president, or for president and vice president, mean votes for them through their pledged presidential electors.
