A shitty one.
Romney isn't hard to figure out for people who've paid real attention to his political career. He hides it well from the public eye only because the media refuses to call him out on his massive flip flopping. Here's where Mitt Romney really stands on issues, no matter what he currently says:
1. At his core he's a corporate/wealthy feudalist. He truly believes that the rich know what's best and that the rest of us should be happy they're willing to take the lead and show us the way forward in life. Internally he finds it insulting that the poor would even question the merits of this belief. Corporations have your best interest at heart because you're a cog in the machine and no corporation wants defective cogs, so stop squeaking so damn much.
2. On healthcare - He honestly doesn't give a shit about healthcare other than what is provided at the very top end of the sector, and that healthcare companies remain a strong Wall St. play. This is why he and his ilk talk about the American healthcare system being the best in the world. Because all the absurdly priced top end services aren't out of their reach. He truly believes that what we have now (minus Obamacare) is perfectly fine and if the poor wanted to live longer they'd do better at life, make more money, and be able to afford better care.
3. On taxes - Corporations and the wealthy should be effectively tax exempt, as it's by their largess that the rest of us survive. If only we were to unshackle them with the burden of taxation they would be free to stimulate our economy in the directions they saw fit, which thanks to their superiority would clearly be in the best direction for everyone. The taxes needed to run his dominant military can easily be raised from the lower and middle classes, who should be given the yolk to motivate them.
4. On foreign policy - means to an end. The major corporations from the U.S. now need a global stage upon which to work, and therefore it is the job of the federal gov't. to grease the skids for those corporate endeavors. Overall he would really like to just be able to flex American muscle and get what he wants without having to actually go to war. That is, unless the war is politically expedient. For example, with a President Romney we WILL go to war with Iran in the third year of his first term. Why? Because the U.S. electorate has shown a strong hesitancy in the past to remove a POTUS during a foreign engagement if they can avoid it and because it would further free up more middle east oil for U.S. based corporate consumption. The fact that it would tickle Israeli hardliners pink is only a bonus.
5. On immigration - generally doesn't care about the difference between poor white people born in the U.S. and poor brown people born somewhere else. This is why he seriously thinks his "self deportation" shit is a good idea. Obviously if we just have them all start from ground zero we'll have plenty of need for brown labor and import as much labor as is needed to get the jobs done.
In short, Romney's goal is to have a limp wristed domestic gov't. that could never stand up to the wealthy or major corporations, while at the same time constructing a massive military. The end result is the wealthy and major corporations effectively controlling a massive military that will strategically aid them in propagating their influence across the globe. To make matters worse, he would also celebrate the kind of corporate sovereignty that major global players like Exxon Mobile already espouse, so it's not like these corporations would steer the military towards what's best for the U.S. and it's people. Instead they'll be selling the U.S. out through the back door while beating the drums for major U.S. support in all their more public endeavors on the front end.
