There’s more bad news for Mitt Romney heading into tonight's debate. A new NBC News/Wall Street Journal/Telemundo poll shows President Obama has a commanding 50-point lead among Latino voters. Seventy percent of respondents said they are backing the president as opposed to 20 percent who are behind Romney. Obama now has a 73 percent approval rating with this key demographic, up 11 points since August. Fifty-three percent view Romney unfavorably. Obama has enjoyed broad support from Hispanics for most of the election cycle, but the data shows that the Romney campaign’s efforts to chip away Latino votes aren’t gaining traction.
