Republican presidential candidate Mitt Romney got a rousing response last week at the University of Miami when he was interviewed by Univision. The network’s moderator later said that was because the Romney campaign couldn’t fill all the seats allotted for student supporters and bused in activists to the empty seats.

The activists naturally ignored Univision admonitions to hold their applause and cheered wildly for him.

Even so, it’s unclear whether even such great visuals will be enough.

The latest tracking poll from Latino Decisions shows Romney, already struggling to connect with Latinos, sinking further with that key demographic.

Obama leads Romney 69-24 in the latest poll — a three-point increase over last week, where he led 68-26. “That’s within the margin of error,” said pollster Gary Segura, but “the trend over the last four weeks is unmistakable and statistically significant.” Romney’s support had been around 30 percent the week of the convention.

“Anyway you cut it, President Obama appears to be consolidating his advantage among Latino voters,” who once gave around 40 percent of their vote to Bush II. And Latinos enthusiasm for voting has risen dramatically, the poll found.
