GAC doesn't give us the link to the fellow who makes this observation, but I have no reason to doubt that the observation is entirely true. Problem is, it's incomplete. If we look at Alexander Cockburn's description in The Nation:
On March 23, 1983, a friend of mine watched as a naval officer and a defense contractor in the Fort Myer Officers' Club in Virginia listened impatiently as Reagan churned his way through a longish overture to his excited launch of Star Wars. Then, as Reagan began to token forth the billion-dollar feeding trough of SDI, they screamed to each other in incredulous delight, "He's going to do it...he's doing it...he's done it! We're rich, we're rich!" With these words, they both made a rush to the telephones.What's that you say? That, somehow, what motivates the already-wealthy and the not-so-wealthy are in some strange way distinct from each other? That's obvious nonsense. Out of the $3.8 trillion in the 2014 budget in total spending, the Farm Bill, which contains the Food Stamps/SNAP program, is 4% of the total budget, keep in mind that the bill also contains farm price supports. Defense is 17%, Veteran's benefits are 4% and transportation, housing, education and energy are 4%, 2%, 2% and 1% respectively. Medicare and Social Security make up around 58% of all spending.
If we look at total Federal spending by county, we can see that rural, i.e., Republican-heavy counties, are pretty flush with Federal cash. So what GAC and TCV are going along with is called "cherry-picking of the data," choosing to look at very small slices of highly select and chosen data to reach really broad conclusions.
