LIKE todo el mundo, chic young Mexican expatriates in Manhattan are loco about el presidente. The other night they gathered at MaÑana restaurant for a feast they called Obama Te Ama (Obama Loves You). Consensus choice for It-girl was Liliana Dominguez (above), who bares all in the new print campaign for Tom Ford. “Every bachelor, married man and gay man there was chasing her around,” laughed one Obamaniac. Also hoisting the Inocente tequila margaritas were co-hosts J.P. Gutfreund and Michel Heredia, designer Brian Reyes, Yaz and Valentin Hernandez and Andrew Bolton, from the Costume Institute.
