will this be the most racist presidential election ever?

My friend Dennis sent me Hullabaloo post that includes this pin on sale at the Republican National Convention Texas State Convention:

According to Dennis, two of the contributors to Hullabaloo are claiming that this will be the most racist election America has ever seen. I don’t doubt that it won’t be infused with racist rhetoric, but using the term “most” might be a dangerous move, given our country’s history for quite blatant and quite subtle racist political rhetoric.
