I'm rooting for Romney. Bolton hasn't seen a war he didn't like and I have no clue what a Rudy has to do with anything foreign policy.
Well, Romney, like Bolton, supported the Iraqi invasion as well.
As for Iran, here is what Romney said when he was running for President:

Romney position on Iran
Well, let’s — let’s start back from there and let’s talk about where we are. This is, of course, President Obama’s greatest failing, from a foreign policy standpoint, which is he recognized the gravest threat that America and the world faced as — and faced was a nuclear Iran and he did not do what was necessary to get Iran to be dissuaded from their nuclear folly. What he should have done is speak out when dissidents took to the streets and say America is with you and work on a covert basis to encourage the dissidents. Number two, he should have put — put in place crippling sanctions against Iran. But instead of getting Russia, for instance, to when — when he gave in our — our missile defense system, to agree to — to stand with those crippling sanctions, he gave Russia what they wanted, their number one foreign policy objective, and got nothing in return...
... Finally, the president should have built a credible threat of military action and made it very clear that the United States of America is willing, in the final analysis, if necessary, to take military action to keep Iran from having a nuclear weapon. Look, one thing you can know and that is if we reelect Barack Obama, Iran will have a nuclear weapon. And if we elect Mitt Romney, if you elect me as the next president, they will not have a nuclear weapon...
... Well, it’s worth putting in place crippling sanctions. It’s worth working with the insurgents in the country to encourage regime change in the country. And if all else fails, if after all of the work we’ve done, there’s nothing else we could do besides mil — take military action, then of course you take military action. It is unacceptable for Iran to have a nuclear weapon. We will not allow Iran to have a nuclear weapon. This term unacceptable has been applied by several presidents over history. And our current president has made it very clear that he’s not willing to do those things necessary to get Iran to be dissuaded from their nuclear folly. I will take a different course. I will make sure that the sanctions, diplomatic pressure, economic pressure and support of insurgents within the country help them become dissuaded to get away from their nuclear ambition.
As for Bolton, here's his position on Iran:
http://www.politico.com/story/2016/11/john-bolton-iran-regime-change-231586EXCERPT:
John Bolton, the former ambassador to the United Nations and a contender to be the next secretary of state, argued Thursday that the United States should support a push for regime change in Iran, calling it the “only long-term solution” to threats the country poses in the Middle East.
“The ayatollahs are the principal threat to international peace and security in the Middle East,” Bolton told Breitbart News Daily, a radio program run by the hard-right website with close ties to Donald Trump. “Now, their ouster won’t bring sweetness and light to the region, that’s for sure, but it will eliminate the principal threat.”

“I think the people of Iran would long for a new regime,” Bolton continued, later suggesting that the U.S. should support opposition groups looking to overthrow it. “I don’t think the regime is popular, but I think it has the guns. And I think there are ways of supporting the opposition that does not involve the use of American military force, that does involve helping the opposition to get a different kind of government.”
“A new government may not be filled with Jeffersonian Democrats, either,” Bolton acknowledged.
