Look, I admire Ryan, Blackburn, and Coburn, and would support any one of them were they nominated. Right now, I support Sarah. When the primaries begin, let the best CONSERVATIVE win.
(Please note my distinctly (sarc)"feminist"(/sarc) point-of-view: I'd love nothing better than to see any of Palin/Bachmann, Blackburn/Palin, Bachmann/Blackburn, etc. All these women possess more testosterone than most of the congressional men...LOL!)
However, merely being eloquent in this or that policy does not reflect on whether that person can make an effective *EXECUTIVE.* It does not make one a LEADER. It does not reflect on one's ability to be Commander in Chief.
Being President and being a policy-wonk who happens to be in Congress are two different things.
Despite how well thought out someone's ideas may sound and how many "yays" or "nays" they can vote--that does not mean they will be able to effectively put their ideas into action and run a country and forge a strong cabinet. It does not mean they have the shrewdness, intuition into people's motives/pscyhology, and even that pinch of charm necessary to forge alliances and handle diplomatic relations.
Communication savvy is vital as well, and savvy isn't determined by how well you can talk with political geeks. It's how well you can communicate with the greater public and culture. VOTERS must feel that they can trust and connect with you. You can't expect to motivate and win over the hearts and minds of the majority of voters merely by treating them like law school professors.
