The Clinton presidency is generally seen as "liberal" - being sandwiched between the two Bush presidencies - but, as we have learned, those words "liberal" and "conservative" can be misleading.
During his first term in office - long before the Lewinsky scandal which made him famous - Bill Clinton signed into law the bill known as the "Defense of Marriage Act" (DOMA), which is the strongest statement to date against homosexual marriage, and which prevents any attempt at diverting federal benefits away from traditional marriages and toward same-sex legal unions.
Now, this may surprise those who see Clinton as a liberal. But Clinton's chief of staff and other close advisers directed him to do this in the same way that they directed him to his other political actions: they kept a close eye on the majority opinion among the electorate. With over 80% of the voters opposed to federal benefits being used to create this novel legal category, Clinton knew that his political future would depend on his following their lead.
Is Clinton a liberal? Perhaps. But perhaps he was simply following the direction set by the democratic process. Which raises a second question: should a president in a democratic society be a "leader" or a "follower"? Although we call him a "leader," we paradoxically expect him to "follow" the majority of the voters.
In either case, Clinton's 1996 support for the Defense of Marriage Act (DOMA) stands as one of the strongest political moves to date against the "gay marriage" movement.
