1960 in 2008

[Vazdul (Formerly Chairman of the Communist Party of Ontario)]

What does 1960 with 2008 numbers mean? Is it a measure of what demographics voted in what year for who put to a different election and timeframe?

I would think that it's merely a measure of changes in electoral votes since 1960. In this case, Kennedy's gains in Texas and other southern states are offset by losses in the northeast and midwest, whereas Nixon would have benefitted greatly from huge gains in California and Florida.
