The last impreMedia-Latino Decisions 2012 tracking poll shows Obama's lead over Romney with Latinos continuing to hover around the 50-percentage point mark:

Among likely Latino voters, those with consistent vote history or have already voted, 73% say they plan to vote for Obama compared to 24% for Romney and 3% undecided. If Obama wins 73% or higher of the Latino vote, it would eclipse the 72% won by Bill Clinton in his landslide re-election in 1996, and mark the highest total ever for a Democratic presidential candidate. ...

On the issue the candidates talk about the most – the economy – Mitt Romney has not been able to move Latino opinion over the 11 weeks of polling. When it comes to moving forward with a plan to fix the economy and create jobs, 71% of Latinos say they trust Obama and the Democrats, compared to 20% who trust Romney and the GOP. These rates are virtually unchanged from 5 weeks ago, suggesting the constant discussion of the poor state of the economy under Obama, by the Romney campaign has done little to persuade Latino voters.
