$$$$ is a big part of it - he's buying the nomination plus he has done a great job of positioning himself as the most electable (so not true) of the group. The comments I hear are "I like xxx but he doesn't have the money or organization to go against Obama and Romney does." Personally, I think Romney is Obama-lite in many ways & won't be able to demonstrate a wide gap on the issues between himself & Obama ... and the incumbent will win.
Wildlife Protection Act of 2010!?!
Relocating entire rodent families!?! Is that re-districting?
I ask the question: Does anyone REALLY believe that the GOP doesn't have as much money and whatever they need to go after Obama? This “he's the only one” is just the meme the Elites and their media synchopants use to get the candidate they want.
