Lame.
There was no "Vow".
Stop pushing liberal "make believe", it is dishonest.
No, not "just like Limbaugh said".
To suggest such is dishonest.
Context is everything.
Limbaugh's comment,
in context was to leave to get health care elsewhere.
Here is the relevant portion of the Question asked.
If the health care bill passes, where would you go for health care yourself?
Here is the relevant portion of his answer.
I’ll just tell you this, if this passes and it’s five years from now and all that stuff gets implemented — I am leaving the country. I’ll go to Costa Rica.
And the context of that answer is driven home by him further saying he wouldn't go to Cuba for healthcare either.
Which is all confirmed in the audio provided at your above link.
And then even if a person chooses to ignore context and lamely thinks it only had to do with leaving the Country there was a caveat attached to it, which was;
"and all that stuff gets implemented".
Well all that stuff didn't get implemented, the "risk corridors" were prevented from going into effect.
