Actually, I don't really know how modern it is, but Repubs have developed an extremely effective approach to convincing people of the "rightness" of their political views.
The one overarching objective of this process is to turn somebody into somebody he's not.
eg 1:
Sarah Palin had no real chops as a politician, and certainly no great knowledge as a citizen (or as a human being for that matter), but the GOP needed us to think she was ready to serve as VP so they mounted an all-out campaign to turn her into some kind of Statesman Savant.
eg 2:
John Kerry is a mostly honorable guy and (as much as possible, I think) a legitimate war hero, but the GOP couldn't afford direct comparisons between him and W, so in 2004 they set about turning Kerry into a French-ified flip-flopping coward who lied about his war record to get medals blah blah blah.
This shit works because too many of us just don't have the time or the inclination to try to sort it out and find what the truth really is.
"A long habit of not thinking a thing wrong gives it a superficial appearance of being right."
Thomas Paine
Sounds good, doesn't it? Now, maybe you trust me to verify the stuff I put in here and maybe you don't, but how many people are going to look at that quote and just accept it at face value, versus the ones who'll take 45 seconds to Google it and at least make a cursory effort to check it out?
Enter Thomas Jefferson. Even the the jerkiest of "conservative" jerks know they're not gonna make it to where they wanna go by sliming Tommy Jeff, so there's an ongoing effort on the part of the Wingnuts to co-opt Jefferson, and turn him into a guy who said things that seem to support the Christianists' point of view.
Some of what Mr Jefferson
actually had to say:
"History, I believe, furnishes no example of a priest-ridden people maintaining a free civil government. This marks the lowest grade of ignorance of which their civil as well as religious leaders will always avail themselves for their own purposes."
"In every country and in every age, the priest has been hostile to liberty. He is always in alliance with the despot, abetting his abuses in return for protection to his own. It is easier to acquire wealth and power by this combination than by deserving them, and to effect this, they have perverted the purest religion ever preached to man into mystery and jargon, unintelligible to all mankind, and therefore the safer engine for their purposes."
"The Christian religion, when divested of the rags in which they [the clergy] have enveloped it, and brought to the original purity and simplicity of it's benevolent institutor, is a religion of all others most friendly to liberty, science, and the freest expansion of the human mind."
"Millions of innocent men, women, and children, since the introduction of Christianity, have been burnt, tortured, fined, and imprisoned; yet we have not advanced one inch toward uniformity. What has been the effect of coercion? To make one-half the world fools and the other half hypocrites. To support roguery and error all over the earth."
Some of the bullshit they want you to buy:
"Sir, no nation has ever yet existed or been governed without religion. Nor can be. The Christian religion is the best religion that has been given to man, and I as chief magistrate of this nation am bound to give it the sanction of my example." monticell.org
"Without God, liberty will not last." monticello.org
"The Bible is the source of liberty" monticello.org
Take nothing for granted. Always check, especially when it seems this or that "quotation" attributed to a "Founding Father" seems to be in near-perfect alignment with any particular ideology. Let's be careful out there.
