The Secret Service put Biden under their protection right before the news broke he was Obama’s veep, but this appears to be a different situation…

If security sweeps are the giveaway, former Massachusetts Gov. Mitt Romney may be on the brink of being selected as Sen. John McCain’s (R-Ariz.) vice presidential running mate.

According to sources with strong Michigan ties, the Secret Service has conducted a security sweep of the home of Romney’s sister. Romney was raised in Michigan, where his father served as governor.

However, one campaign operative familiar with the working of a presidential-level campaign cautioned that a sweep of such a location could have been conducted in advance of Romney appearing as a surrogate — not the vice presidential nominee — at an upcoming McCain campaign stop in Michigan.

Still, why would Romney’s family be getting any sweep if he’s just a surrogate at a rally yet again? Does this happen every time McCain speaks in a certain location? They sweep the surrogate’s sister’s house? That doesn’t make any sense to me.

What do you think?
