Over the past month, Ohio junior senator Rob Portman has appeared to be the flavor of the month for those handicapping the VP race.  Portman, whose big drawback apparently is a lack of “pizzazz”, hasn’t exactly defused the buzz surrounding his potential candidacy.

Portman, in an apparent attempt to beef up his foreign policy credentials, recently took a visit to Israel and met with Prime Minister Benjamin Netanyahu.

On the other side of the spectrum, the former “favorite” Marco Rubio has received some endorsements from some big fish in the GOP pond.

Jeb Bush, the former Governor of Florida, denied interest (or being vetted) in the VP slot and instead offered his endorsement of Marco Rubio.

While some could see the younger Bush’s endorsement of Rubio to be a spot of geographic nepotism, Rubio also received a boost from former Arkansas Governor and ’08 Presidential candidate Mike Huckabee.

Huckabee, who like Bush denied interest in the slot, suggested that the “better pick would be Marco Rubio”.

Now Portman would be a safe pick for Romney.  He would be submissive to Mitt & also seems to be smart enough (or just boring) to not generate much controversy on the trail a la Sarah Palin.  Portman has some experience in the George W. Bush administration as the Director of the Office of Management and Budget and that could be seen as a strength for Team Romney as they tout their budget skills.

Rubio, a favorite of the Tea Party, seems to be the future of the GOP.  However, he’s a big risk as his relative inexperience would be brought to the forefront.  Rubio seems to be the type that can excite the base and also make Florida that much closer on Election Day.

Now other candidates such as Kelly Ayotte, Bobby Jindal & Chris Christie can not be ignored, but it seems speculation has stuck on Portman or Rubio.
