I was talking about racism, not politics. Of course a lot of people that don't like Obama don't like him for his liberal/Democratic policies. Racism, though, was exacerbated by Obama's election and it's been push and push back as far as racial tensions go. Two different animals, politics and racism.
Obviously racism became a central issue upon President Obama's election. After all, it was (supposedly) a sign that racism was ending in the US. However, the exacerbation was on the part of the Obama administration in their actions be it the Philly election polls, becoming personally involved in local issues such as the Zimmerman case, Ferguson and the like. President Obama himself, or more commonly, through his appointed representatives, continued to show bias to African-Americans over European-Americans.
That's the part that enflamed racism in this country.
