It's not over until the fat lady sings, and Obama has so many skeletons in his closet in addition to being such a screw-up when required to be extemperaneous, that Ms Hillary would be well-advised to just hang in there.
After all, Obama is trudging along under the weight of:
1. Black racist associations including his Rev. Wright and Minister Louis Farrakhan of the Nation of Islam, and the current pastors of Trinity..
2. Terrorist associations including William Ayers, and his wife Bernadette.
3. Received some $300,000 in bribes from Rezko and an Arab financier for purchase of his home property in return for "favors."
4. Rezko's conviction before the convention might result in Rezko "ratting out" Obama on other deals for leniency.
5. Activity as an Alinksy street agitator inciting racial antagonism.
6. Hate America associations.
7. Demeaning attitude towards women.
8. Wife's anti-white history and lack of love of country.
9. Islamic family connections displayed in Africa.
10. Philanderer.
11. Druggie - user and dealer.
Well, that's just some of the history affecting Obama's viability. What secret will out that will explode with sufficient power to destroy his viability as a candidate, if and when, is always in the wings.
There's a time-bomb ticking there because he has been a bad boy throughout his life and has maintained and still maintains, unhealthy associations.
How much is excused for this unfit candidate?
