The reason is that the Republican presidential campaign is drowning in cash but nonetheless a lost cause.
If the Republican Presidential campaign is such a lost cause, why is Obama saving all of his money? Any electoral vote over 270 will be wasted money for Obama. Getting over 380 electoral votes rather than 272 gets Obama absolutely nothing. Republicans are not going to work with him no matter how many electoral votes he gets. This money could be used to keep the Senate and take back the House.
I suppose the people in charge believe that taking back the House in 2012 is
also a lost cause.
The people in charge don't tend to think big or out of the box, of course.
