So Roll Call, a Capitol Hill newspaper reports:
Newly emboldened Republican lawmakers in Iowa and New Hampshire have sharpened their focus on blocking gay marriage rights, thrusting a wedge issue into the spotlight just as candidates start wooing voters in the most important states on the presidential primary calendar.
The debate over the divisive social issue has recently neared a boiling point in both states, even before the Obama administration decided to oppose the Defense of Marriage Act. Already there have been packed state house hearings in New Hampshire, Iowa Supreme Court judges ousted and groups threatening oaths for presidential hopefuls. (source)
