That he is mistaken. Nothing in either the Senate or the House bill allow for sale of insurance across state lines. And five states currently allow sale of insurance across state lines, some going back to 2010, and in none of those states is there any evidence that it lowered insurance premiums. In fact, in none of the five states is there any evidence that any out-of-state insurance companies were willing to sell policies to the residents in any of the states.
This is, of course, assuming that Limbaugh was not mistaken in the first place when he said the president said that.
Limbaugh was playing comments from the President. Those weren’t the words of Rush. Insurance companies don’t want to sell across state lines. They like their individual state monopolies.
