I would say that this is a sign that she is not running in 2016. But, these days, who knows? She could be doing the speaking tour to warm up for a political run in 2016.

EXCLUSIVE: Former Secretary of State Hillary Clinton will hit the paid speaking circuit this spring (likely April or May) and has selected the Harry Walker Agency, which represents President Clinton, as her agent. Industry officials expect that she will be one of the highest paid speakers in the history of the circuit, with fees well into the six figures in the United States and abroad. Secretary Clinton will likely do some speeches for no fee for causes she champions, and expects to occasionally donate her fees for charitable purposes. Clinton, who will maintain her homes in Washington and Chappaqua, is also beginning to make decisions about the book she has said she will write, an account of her four years as secretary of State. Non-profit work will be another component of her new life, perhaps through her husband’s foundation or one of her own. — HILLARY CLINTON UNVEILS FIRST PHASE OF NEW LIFE -POLITICO.com

Either way, I wish her the best. I think it would be interesting to see Hillary Clinton and a Republican woman run for President. It would make for some interesting debates, especially on Abortion. If anything at all, it would be fun to see who could out-harpy the other. You know, two feminists, screaming at each other as to whom was the more self-important. It would, if anything, make for some very funny TV.

Just my opinion.
