Here's some free, unsolicited advice for @spencerpratt.
If they haven't already, you will soon be bombarded by professional losers portraying themselves as brilliant consultants your campaign just cannot do without.
Tell them to go pound sand.
You need to do something radically different, not marginally, which is nothing they can offer you, otherwise you will obviously lose in spectacular fashion and just end up the latest guy who got everyone's hopes up.
California is littered with campaigns like this.
Don't be afraid to be different, to do things all media and the professional loser class will laugh at, because that's what it will take to make a go at this thing. You'll need to talk to people the right never talks to, go into neighborhoods the right dares not ever venture, and it's going to make a lot of people uncomfortable.
But doing that and more is your only hope to not waste your time and energy. Use organizations who supported the president like 10xVotes (if they are even willing to do it), rather than paying shitty GOP door-knocker companies that will never walk the neighborhoods you need to visit. It would also be the best, most effective way to build a ballot curing and chasing operation this late in the game.
If you thought it was a rushed process and the city was big before Round 1 of the Jungle Primary, wait until they start drumming you in Round 2.
Despite big talk from everyone, it is the unsung orgs who have been most successful in breaking the social stigmas and barriers that come with trying to reach out to new demographics, aka realignments.
Bottom line: do not do anything Republicans would instinctively do or run a playbook even remotely close to the one they run.
