According to NBC which I am currently watching, the field is narrowed down to Mitt Romney, Rob Portman, and Tim Pawlenty.

Sam has predicted Romney. I have predicted Pawlenty. We’ll see which one of us is right, or if he goes with the dark horse pick of Portman.

[UPDATE]: Jim Geraghty is hearing that it is Pawlenty, and HotAir puts that and other clues together to make a compelling argument for this being the case. Stay tuned…

[UPDATE - Tues. Morning]: I am flipping news channels this morning over my morning joe (the drink, not the show) and on MSNBC they are currently talking about this. According to MSNBC the McCain VP “shortlist” includes Jindal, Pawlenty, Portman, Lieberman, Romney, and Ridge. MSNBC is also saying that the buzz is suggesting that Pawlenty may be the one. As for Obama’s pick, apparently VA Gov. Tim Kaine is very high in consideration, among others such as Dodd, Bayh, Clinton, and Biden.
