Rick Santorum gets used to a little more attention

For a long time, Rick Santorum's campaign seemed to be going nowhere. There was even an occasion when just one person showed up to one of his campaign events, according to The New York Times.

How times can change. Now that he is running higher in the polls, he can't even sit in his car without being buzzed by the media. And on Monday evening, he was bestowed with the somewhat tarnished honor of a tweeted endorsement from Rupert Murdoch.

Will Santorum's star burn ever brighter, or will it fizzle out like those of several candidates before him? Stay tuned to NBC Politics in the days to come.
