Socially conservative Ireland votes today on marriage equality. This heavily Catholic country is expected to be the first nation in the world to approve same-sex unions through the referendum process (recent polls suggest that 58-64% of eligible voters will approve marriage equality). Whether these poll numbers translate into actual votes is another question. Historically, polls underestimate opposition to same-sex marriage by 5-7%. People are sometimes "shy" about voicing opposition to same-sex marriage for fear of being labeled a bigot, which, of course, they are.
