Honest political question from an American. In American politics, it's usually (especially during the campaign) for the Presidential candidate to be relatively above-the-fray, focused on their vision of the country, and so forth, while the VP candidate is basically the attack dog to say the asshole things (see : Joe Biden, Sarah Palin, Dick Cheney, and Dan Quayle).
So, is there any reason why it wouldn't for Shorten to be the "above the fray guy" and basically give Albanese free reign to wreck shit and do things like Biden did (ie. "Oh, I'm totally for gay marriage." "This airport looks like crap.")?
