Just ask John McCain, and he'll tell you. Your Vice Presidential selection can have a big impact on your campaign.
From a consultant's list of possible contenders, WHNT News 19 Political Analyst Dr. Jess Brown says he's got some favorites, "The two on the list of fifteen I saw were Senator [Rob] Portman of Ohio and Senator [Pat] Toomey of Pennsylvania."
The two may not be the most recognizable candidates for the undercard, but they both come from major swing states.
But the issues bring Senator Rob Portman to the foreground.
Dr. Brown assesses, "I might give a slight advantage to Senator Portman, because he's been a Budget Office Director. He can talk the economy and taxes and the budget issue."
In a campaign season likely to be dominated by the economy, Portman's experience not only dealing with economic issues but also talking about them could prove an asset.
Just as important, Brown says while Sarah Palin brough a certain excitement to the McCain campaign, he believes Mitt Romney will go for a candidate that can deliver at least one key state swing state.
Dr. Brown concludes, "Just look at that independent voter spectrum and ask which candidates have proven in a highly diverse state, a mainstream state, a state you've got to have in a presidential election typically, like an Ohio, Pennsylvania, find somebody who's demonstrated they can get independent voters - and on the list I saw, that's Portman and Toomey."
