Nothing has changed in the nearly 100 years since Confederate aficionado and leftist zealot Woody Wilson spoke in favor of his DemonRAT-sponsored terrorist wing, the Ku Klux Klan. As it was then, so it remains today, the KKK is an outfit tightly bound to the party that opposed Lincoln and hated Ronald Reagan. The superficial matter of skin color aside, the Klan otherwise marches (with that flag) in lockstop with hussien's liberal policies favoring Big Government and Big Labor.
President Reagan never posed himself with the Confederate battle flag. Neither did Calvin Coolidge. But a lengthy list of 'RAT presidents proudly wrapped themselves in that symbol. And I never saw one at a Tea Party event. Likewise with Ted Cruz.
