Ruben Diaz, Sr. is on the warpath again, this time blasting Mayor Bloomberg and City Council Speaker Christine Quinn for supporting a same-sex marriage bill when, he says, they should really be focusing on the renewal of the state’s rent stabilization laws, which expire on June 15.But, over the past year and a half, Diaz himself has done his share to divert attention away from the strengthening of rent regulations. “I would love to see Mayor Bloomberg and Speaker Quinn set their priorities straight and spend a day in Albany to push for an extension of our affordable housing laws before the deadline passes,” Diaz wrote in a statement sent out last week after Bloomberg and Quinn had trekked to the capitol to lobby for gay marriage. “The Rev” has spent a fair amount of his own time focusing on same-sex marriage – he organized a rally last Sunday against its legalization – but he says that was just in response to other politicians pushing the issue.”I’m not putting [same-sex marriage] as a priority,” he said in a phone interview last week.His priority, he says, is the Emergency Tenant Protection Act, the set of state laws that protect the rent-regulated status of hundreds of thousands of apartments in the Bronx, and about a million across the city. Tenant advocates have been pushing to see the laws not only renewed before the June 15 deadline, but strengthened to close some of the loopholes that landlords use to hike rents in regulated units.Diaz said the mayor and Gov. Andrew Cuomo were ignoring the approaching June 15 deadline, and that, he says, “is a crime.”
