Today's installment of campaign-related news items from across the country.
* There hasn't been any major shake-up on Hillary Clinton's staff, but she is adding Jen O'Malley Dillon, the former deputy campaign manager for President Obama's 2012 re-election campaign, to the Clinton team.
* As attention now shifts to South Carolina, which hosts its Democratic primary in about two weeks, Clinton unveiled a new ad yesterday called "Broken," which focuses on systemic racism in the criminal justice system.
* Chip Englander, who ran Rand Paul's failed presidential campaign, has decided to join Marco Rubio's operation.
* It seems hard to believe, but Rep. Todd Young, the leading Republican candidate in Indiana's U.S. Senate race, "may not have submitted enough valid petition signatures to qualify" for the ballot. The Indiana Democratic Party is moving forward with a challenge to Young's eligibility.
* MSNBC reported yesterday that Bernie Sanders, throughout his Senate career, "has been a regular presence at luxurious Democratic fundraising retreats, according to more than a half-dozen lobbyists, donors and former Democratic Senatorial Campaign Committee staff members with whom he attended the events." It follows a similar report about Sanders attending a 2007 fundraiser on Martha's Vineyard, which included wealthy lobbyist donors.
* The field of Republican Senate candidates in Florida will apparently grow to five, with homebuilder Carlos Beruff poised to throw his hat in the ring.
* An interesting catch from CAP Action, which found that no Republican presidential candidates have mentioned the crisis in Flint, Michigan, through any of their social-media accounts.
* Former Virginia Gov. Jim Gilmore (R) doesn't seriously expect to be the Republican nominee for president, but he apparently intends to keep running anyway. "I don't think we'll win this thing," he told a supporter yesterday, "but let's see if we can get some recognition."
