Colorado, Nevada, New Mexico and Florida all have a significant number of Hispanic voters. President Bush narrowly won all four states in 2004, and they could all be hotly contested this year.

"When you look at the battleground states, at least four of them are very heavily Hispanic," said Simon Rosenberg, head of a think tank called NDN, formerly the New Democrat Network. "We will see more (campaign) media heaped on Hispanic voters than at any time in American history."...

"Just looking at the demographics, whichever party ends up winning the Latino vote will be the majority party in the 21st century," Rosenberg said.
