The new trailer for "House of Cards" season 4 shows Frank Underwood's (Kevin Spacey) campaign for re-election but his wife Claire (Robin Wright) was nowhere to be found.

In the season 3 finale, Claire was seen walking away from Frank, leaving him in the middle of his battle for re-election. Numerous speculations claim that Claire might be coming back to patch things up with her husband and some even thinks that the couple might be adopting a child. However, in the new teaser video, Claire cannot be seen supporting her husband.

International Business Times reported that some are speculating that based on the trailer, Frank and Claire might be making their separation final and they will announce it in public. Frank is known to use unconventional ways to get what he wants and he has always prided himself with that. Other sources speculated that the couple will be working separately this time as Claire still doesn't know what she wants to do now that she separated herself from her husband.

Michael Kelly, who plays the role of Doug Stamper, teased in an interview that "House of Cards" season 4 will focus on both Frank and Claire. He explained that the show will focus on Frank's determination to become the president again. Kelly was earlier confirmed to return to the show and he teased that Frank is much more efficient if Doug is by his side. In the teaser videos for season 4, Frank can be seen being confident with his campaign.

Christian Today reported that the teaser video for season 4 also shows Frank's campaign video where he can be heard saying, "America, I'm only getting started." It seems like with or without the support of his wife, Frank will do everything in his power to win the coming presidential elections.

"House of Cards" season 4 is scheduled to premiere on March 4 on Netflix.
