Unless Romney decides to run again, he's irrelevant to the 2016 race.
Endorsements usually don't matter. When the endorsement comes from a two-time loser with no die-hard constituency, it matters not at all. On the fundraising side, sure Romney could help someone out a little. But, Mitt Romney isn't going to spend hours every day begging his friends to send Chris Christie money.
The only question I would have is who do Romney's campaign staff work for. Romney did amazingly well in Iowa for a cold, weird big business conservative with no real message. If I were a Republican running in Iowa, I would want to hire some of his staff. Maybe not the person who designed ORCA.
Imagine if the ORCA people were in charge of the Obamacare website.
