Presumptive Republican presidential nominee, Mitt Romney, has yet to announce the selection of his vice president candidate. Such an announcement is not expected before the Republican National Convention. Yet that doesn't keep plenty of political observers from discussing and speculating who the eventual nominee will be.

VP Odds: 18:1

Name: Gov. Bob McDonnell

Age: 58

State: Virginia

Current Position: Governor of Virginia

Previous Position: Attorney General of Virginia, Member of the Virginia House of Delegates, Former lieutenant colonel of the US army

Notable for: Virginia Governor Bob McDonnell endorsed Mitt Romney early on, before the race started to take shape. However, McDonnell’s decision to reinstate Confederate History Month without acknowledging slavery — an omission he later rectified — is being seen as a potentially career-threatening misstep, especially in regard to potential VP candidacy.

Quote: "The proclamation issued by this Office designating April as Confederate History Month contained a major omission. The failure to include any reference to slavery was a mistake, and for that I apologize to any fellow Virginian who has been offended or disappointed.”

VP Odds: 28:1

Age: 51

Previous Position: Resident Commissioner of Puerto Rico

Notable for: Fortuno avidly supports the movement for Puerto Rico to gain statehood.

Quote: “We have been part of the United States since 1898; natural-born citizens since 1917. Our men and women have served in greater numbers than most states since then. And I believe that it's the right thing to do in the 21st century, to allow almost 4 million American citizens to express our will and then to work with the White House and hopefully President Romney to address this issue."

VP Odds: 499:1

The odds for several of these politicians are slimmer than others in terms of being named as a running mate. However, recalling the 2008 GOP convention, John McCain surprised Americans with his choice of Sarah Palin as his VP candidate. Given the outcome of 2008, we can guess Romney's campaign will be ultra careful and strategic with their choice. As such, it's anyone's guess who Romney will ultimately choose.
