If Obama takes Texas and comes close in Ohio then I think she packs it in. I don’t think that the Clinton camp thinks he can win in November so I think they cut their losses start laying groundwork for 2012.
The interesting thing is the fact in 2012 she is up for reelection for Senator from New York. Does anyone know, can her name be placed on the NY primary ballot for both Senator and President? Would she pledge not to run for Senator? Bob Dole actually resigned his Senate seat in '96, he did not have to, but did anyway. Or will she keep open the Senate run as a "fall back", if she fails again through the presidential primaries.
