Do you have any evidence behind your statement? Given a choice of concrete evidence (exit polls), and your anecdotal evidence, I have to side with the concrete evidence.
And so far the concrete evidence is telling me that Santorum is the strongest conservative by quite a wide margin.
What do you see as the constitutional obligations of the federal government? Do you believe that the federal government should treat the unborn the same way as everyone else?
Rick Santorum is a big-government pseudo-conservative. He has consistently voted to increase the size and scope of government in our lives, just as has the rest of the establishment wing of the Republican Party, of which he is a member in good standing.
Exit polls aren't "concrete evidence." Exit polls that you are reffering to only guage peoples' opinions about themselves. They're no more "scientific" or "definitive" than anything else. The simple fact of the matter is that a lot of Santorum's supporters, who may actually believe themselves to be "very conservative," are actually big-government, semi-socialistic, progressive social gospel supporters. Which means they are not true conservatives.
