Nationally, Bush won some 40 percent of Latino voters in 2004. This year, the Republican share of the Latino vote dropped to 31 percent, while the Democratic ticket took 66 percent.

An influx of newly registered young voters is another factor widely credited with swinging the victory to the Democratic ticket. And the Democratic nominating convention was held in Denver, the state's capital and biggest city, which gave the candidates high visibility here.

Immigration is among the most important issues to many Latino citizens, according to polls. Even though Senator McCain was co-sponsor of a comprehensive immigration reform bill that died in Congress in 2006, he took a harder line on the issue during the campaign.

Many Latinos blame conservative Republicans in the House of Representatives, such as Tom Tancredo, who represents the Denver suburbs, for sinking the bill and pushing for criminalization and mass deportation of undocumented immigrants.
