The whole thing is just wishful thinking. In addition to the points you make, the article claims Texas is going "winner take all". Texas is almost certainly NOT going "winner take all". The Santorum campaign is pushing for such a change, but the odds of that actually happening are next to none and none.
I agree. It is funny that a lot of the “non-Romney” supporters made a big fuss over changing the rules after the game had started, but now they want to do the same in Fl and Az.
