The answer to "How" is to recall the tactics of indoctrination used in POW camps during the Korean War. Repeating over and over and over the same propaganda until the public is so exhausted, they have not but to accept it as fact.
As a former Republican of 33 years, I left the party when I was shocked at the way Bush was elected in 2000 and 2004. In my mind, it was just the beginning of an end to democracy in this country. This is borne out by the type of redistricting Texas Tom Delay and his bosom buddy got into trouble for...K-Street lobbying and redistricting using shady tactics. Isn't that exactly what the GOP is doing in the red states? Denying the handicapped and elderly the right to vote because of diminished mobility? Isn't that what they are doing when they vote down laws related to women's rights?
These red staters lost the Civil War and have been stewing over that loss ever since. The only good for them that came out of that loss was the ability to use blue state tax revenues to support their archaic industries so they can keep their unemployment low. Until you check out the disparity in the salaries in red states and lack of progressive advancement for employees.
These old time Confederate mentalities are used to bullying, bossing and keeping their slaves under their thumb by keeping poverty at a high. Isn't that what they've done since Reagan?
There are Americans who will not ever accept these red anti-government, anti-president clowns as anything but what they are: Backward, selfish ingrates with overblown superiority complexes based on their all too insular educations.
