Why the Bull Moose?
The original Bull Moose Party was founded in an America under siege by political corruption and moral capitulation. Power was held by just a few wealthy robber barons whose interests had diverged from those of the average American, and who used their immense fortunes to buy off the politicians who could have stood up to them. This crisis of confidence is what moved Theodore Roosevelt, then a progressive Republican, to break with his party and create a movement that couldn't be bought and wouldn't be broken.
More than a century later, America faces the same issues, facilitated by the same actors, met with the same abdication from the establishment. The robber barons of today harbor the same resentment toward the Americans who buy their products and pay for their subsidies. The establishment of today proclaims courage, promises change, and delivers nothing of substance.
Thus the moment demands, as it did in 1912, a movement that is unapologetically strong in its moral stature and unwavering in its commitment to change at any cost. There can be nothing less.
