Today's installment of campaign-related news items from across the country.* If the new ad from the Congressional Leadership Fund in Georgia's upcoming special election is any indication of their internal polling, Republicans are starting to panic a bit about Jon Ossoff's (D) chances. The first round of voting is on April 18. The runoff, which will likely be necessary, will be June 20.* Not satisfied with his criticisms of the House Freedom Caucus in general, Donald Trump has started publishing tweets going after specific members of the caucus by name.* On a related note, Rep. Mark Sanford (R-S.C.) said the White House explicitly threatened to run a primary challenger against him if the congressman opposed the party's health care plan.

Bernie Sanders (I-Vt.). "All of you who are Bernie supporters ... I need you. I want you. I want to talk to you. I want you to be part of our effort," McCaskill said this week, adding, "We can't get divided in a state like Missouri, or we're cooked."* Though it took a while to resolve, Steve Bannon "will not be charged in connection to an investigation of his registering as a voter in Miami-Dade County, Florida, despite reports last year that he had not lived at his listed address for months."
