Sean Trende is skeptical:
While the Latino vote is frequently portrayed as a critical voting bloc, in truth it is concentrated in only a few swing states with just a handful of electoral votes. The only states where Latinos make up more than 10 percent of the electorate are: Arizona (16 percent of the electorate in 2008), California (18 percent), Colorado (13 percent), Florida (14 percent), Nevada (15 percent), New Mexico (41 percent), and Texas (20 percent).
Of these, only Colorado, Florida, and Nevada are swing states; New Mexico and Arizona are at best borderline swing states. In Florida, the Latino vote largely (though decreasingly) comprises voters of Cuban descent and is therefore atypical of other Latino electorates. So in the end, we’re talking about Colorado and Nevada as the states where this is likely to produce dividends of any size, for a total of 15 electoral votes.
Ed Kilgore pushes back.
