Right-wing radio shock jock Rush Limbaugh is worried that Barack Obama is helping lesbian farmers take over the US.

The outspoken host, who helms the most listened-to talk-radio program in the US, made the bizarre comments earlier this month on his show.

After hearing that the US Department of Agriculture is helping to sponsor the first Iowa LGBT Rural Summit as part of their billions of dollars of farming subsidies, he got a little bit carried away with a knot of connected conspiracies.

He said: “Have you heard the latest Democrat scam? Have you heard about the Agriculture Department’s financial grants to lesbian farmers?

“I’m like you; I never before in my life knew that lesbians wanted to be farmers. I never knew that lesbians wanted to get behind the horse and the plow and start burrowing. I never knew it.”

Of course, he as a paranoid theory why Obama might be trying to help lesbian farmers take over the world.

He said: “Rural America happens to be largely conservative. Rural America is made up of self-reliant, rugged individual types. They happen to be big believers in the Second Amendment.

“So here comes the Obama regime with a bunch of federal money and they’re waving it around, and all you gotta do to get it is be a lesbian and want to be a farmer and they’ll set you up … They are trying to bust up one of the last geographic conservative regions in the country, and that’s rural America.

“But apparently enough money can make it happen, and the objective here is to attack — they’re already attacking suburbs, and that has been made perfectly clear by what happened in Milwaukee.

“And they’re going after every geographic region that is known to be largely conservative. They never stop, folks. They are constantly on the march.”

Of course, if Obama really wanted to disadvantage Republican farmers, he would probably start by cutting down the $20 billion paid out annually in farming subsidies, but Rush isn’t big on the whole logic thing.
