Virginia pol Eric Cantor’s primary defeat was blamed by some GOP insiders on his spending, plus “too much time on the road and in the Hamptons.”

But since the loss last month, the outgoing House majority leader has been almost an East End fixture.

On Sunday, he was seen at the Hideaway in Montauk, which a local described as “a tiny amazing Mexican dive on the docks.” The pol and his party were flanked by four burly security guards who’d arrived in two SUVs. (Perhaps he was drowning his sorrows: The joint’s mantra is, after all, “Tequila for the People.”)

In June, Cantor appeared as a speaker at the Hampton Synagogue in Westhampton Beach, and also at a fund-raiser for state Sen. Lee Zeldin.
