The k street project isn't as bad as Newt working for Fannie Mae. It is more complex and IMO is arguably alright since it was simply an effort to even the odds so to speak of lobbyists being Republican instead of Democrats.
I dunno, to me it sounds like his dirt is about on par with Obama's dirt as Senator, which didn't really sway anyone in the election.

Of course I think without any K street nonsense Santorum is utterly doomed anyway, so hey.
