That could very well happen. Voter apathy on the Romney side because of “inevitably” might result in a lower turnout and a Santorum victory. It’s not “delusional” to say that could happen. Of course, there are at least equal odds that the reverse will happen. I’m still hoping to stop Mittens. Call me “delusional” all you want, but I’m not quite ready to give up all hope.
Don't worry about “voter apathy”. There is a low turn out for every Primary on all sides. And you might want to reframe your definition of “hope”.
You had better “hope” that Santorum does not win, and does the right thing and drops out so we can build a strong offense around a solid candidate to go against Obama.
If this struggle continues much longer, Obama will walk away with it again, because our side of incurably weak and chaotic. That impression alone, will have a major effect on how the ignorant American public votes for a candidate.
