National Democratic Party Chair Ken Martin is said to be in survival mode. That’s how people close to the embattled leader describe his mindset as he navigates a storm of frustration from within the party heading into the November elections. Calls for Martin's resignation are growing louder among Democratic operatives. They're concerned about Martin's fundraising performance and his leadership decisions, among other things. Martin is avoiding media appearances. He's monitoring his critics’ social media posts. And he's refused so far to adopt any meaningful changes. The situation threatens to undermine the party’s momentum in the fight against President Donald Trump’s Republican Party for control of Congress this fall.
