Severely hollow conservatism?

Romney at the at the Conservative Political Action Conference:

"I know conservatism because I have lived conservatism... I was a severely conservative Republican governor... I fought against long odds in a deep blue state....

"Leadership as a chief executive isn’t about getting a bill out of subcommittee or giving a speech. It’s about setting clear goals and overcoming constant adversity...."

Santorum says:

"We will no longer abandon and apologize for the principles that made this country great for a hollow victory in November....

"Why would an undecided voter vote for a moderate candidate who the party isn’t excited about?..."
