The AP reports that the son of Ron and GOP Senate candidate is furious with “senior GOP” leaders. Who exactly? Well, he won’t say. But you can guess:

Republican Rand Paul will begin airing a TV ad Wednesday attacking “senior GOP leaders” for lying to evangelical leader James Dobson.
Dobson, founder of the Colorado-based Christian group Focus on the Family, had endorsed Secretary of State Trey Grayson in the Senate race last week. Dobson called that endorsement “an embarrassing mistake” on Monday and instead threw his support behind Paul.
In the ad, Dobson says he was given misleading information about Paul that led to the errant Grayson endorsement. A narrator says when Dobson learned the truth, he rejected the lies.
Dobson hasn’t identified who gave him the misleading information.
