For Richer, For Poorer

A few days ago in class, we talked about the financial standings of voters and their presidential preference. Voters for John McCain and Barack Obama were clearly from a certain economic standing. Those making under 100,000 dollars a year voted for Obama. Those making between 100,000 and 200,000 dollars a year voted for McCain. And those making over 200,000 dollars a year voted for Obama, as well. This is different from past socioeconomic trends relating to Republican and Democratic voting. Usually, voters making more money tend to lean Republican. This is especially odd because Obama has been clear in his plans to raise taxes for the more wealthy. So why would these voters elect a candidate who would raise their taxes? Do their beliefs that he agrees with override their wish to keep their cashflow steady? This is what I hope is true. What do you think is the reason that voters in specific socioeconomic groups voted for a specific party or candidate?
