I don’t like Romney.... period. However, your post above regarding him granting waivers is the only legal recourse the next President has. Congress passed it and unless the courts rule the whole thing unconstitutional (I am hopeful) only congress can undo it.
I hope the next President attacks Obamacare and the EPA through other means such as funding and executive orders when possible but the bill that Hagosi and Dingy passed must be overturned by congress.
The legislature passes laws and Presidents can’t overturn them on a whim. The founders set it up that way for a reason and it’s worked pretty good.
But, he has still said nothing about supporting repeal now has he?
