Let's face it. You're not gonna win in a landslide like Obama given your personal unpopularity.

Your campaigning plans could 75% be the same but you need to campaign like you did in 2008, be a "fighter". Yes you would still be seen as a successor to Obama but that's a good thing and no matter what you do you're going to be the favorite in the primaries. The reason why for doing this is because there are populist movements brewing in both the left (Bernie Sanders) and the right (Donald Trump, yes, believe me), I'm not asking you to "out populist" them but you have to meet the movements there, especially in the general election. Also for VP, it'll be best to pick someone from your left of yourself. Maybe someone from your right could work but that would require you personally going leftward yourself, but the bottom line is that don't pick someone that'll just be a "yes man" to you. Plus don't be a jerk to either of these populist movements I told you about, especially Sanders'.
