This graph of Mitt Romney’s daily support from Gallup is a perfect example of what being an inevitable but not exactly beloved nominee looks like. From Gallup:

Preference for Republican Nomination, Recent Trend

For the past month Romney’s lead managed to steadily increase and stay relatively high.

During the time period displayed in the graph Romney actually lost Louisiana on March 24th by an incredible 22 points. Looking at the graph, though, you would never have guessed.  Rick Santorum’s big win didn’t even dent Romney’s national numbers.

Romney’s lead is now both substantial and remarkably resilient.  Even if Santorum wins a few big victories in the remaining parts of the Bible Belt, he’s unlikely to change that. At this point barring something truly incredible happening, Santorum has basically no hope of stopping Romney from becoming the nominee.
