So? So is every 'gaffe' done by every presidential candidate in our lifetime.
..and yes, Reagan did denigrate half the country by calling the South the birthplace of the KKK when making a comment about a Jimmy Carter campaign stop.
Acceptance speech does not equal campaign stop speeches.
No, just a select few shitheads that hyperventilate over every news item they read and pretend like it means something in the 'big picture'.
A republican bashing the south is probably the best thing you can do of you're gonna bash something. Slavery, the Civil War and Jim crow are the three darkest stains in our nations history arguably and the south is the center of it all. A republican not going full redneck is one of the reasons 49 states votes for him in 84.
If a conservative found a way to understand and appeal to the people in this country who are scared of the racist bigotry in the republican party it would help them win.
Since 1992 - a Republican has gotten more votes than a democrat for president in only 1 of the last 5 elections. Democrats have gotten the popular vote in 4 of the 5 and two were absolute landslides. If Obama wins this year it will be 5 out of 6 going for the Dems.
The silent majority republican thing is LONG gone, if you want to win as a republican with the demographic shifts of increased minorities, increased women, and Clinton/Bush contrast fresh in people's minds, it would help not to alienate the majority of voters who lean democratic in presidential elections.
