Well, Frank Underwood is promising he’ll do anything for America…but just how far will he go to win the White House in 2016? 

 If this brand new teaser clip for season four of the Netflix smash is to be believed…well, he’s certainly prepared to “dig deep”. 

Speculation is welcomed in the comments (is he unearthing the class ring he buried last season, or is this some kind of allusion to re-planting the seed of the tree that is his once flourishing marriage? Are we reading too much into this? How many days until March 3 again?) but for now…a few tantalising seconds to tide us over.
