Santorum is a good man and has worked for many conservative causes. However, as the list above illustrates, GOP conservatives rallying to him are glossing over his liberal dalliances, much as they initially downplayed Newt Gingrich's open marriage proposals and philandering. Why? Because he is not Romney.
Perhaps conservatives should dig a bit deeper into Santorum's conservative credentials, and compare them with Romney's. The contrast is not nearly as stark as the "he's not Romney" mob attempts to portray.
