Today's installment of campaign-related news items from across the country.
* Hillary Clinton's delegate advantage over Bernie Sanders inched just a little higher over the weekend when she added a net gain of two delegates from the Northern Mariana Islands' Democratic caucuses.
* Following Friday's apology about Nancy Reagan and HIV/AIDS, Clinton published a lengthy statement over the weekend, celebrating those who "really started the conversation" about the health crisis.
* A state judge ruled Friday that 17-year-old Ohioans, who will turn 18 by Election Day, are eligible to vote in tomorrow's Ohio primary. Secretary of State Jon Husted (R) announced soon after that he would not appeal the decision.
* Speaking of the Buckeye State, Mitt Romney will join John Kasich on the campaign trail in Ohio today, making two separate appearances. It is not, however, an official endorsement.
* Polls show Donald Trump well positioned in Illinois' primary tomorrow, but his campaign is so concerned by its weak statewide operation that Team Trump fired its Illinois campaign director over the weekend.
* Is there anything Donald Trump could do that would force Ted Cruz not to vote for him if the frontrunner wins the GOP nomination? If Trump would "go out on Fifth Avenue and shoot somebody, I would not be willing to support Donald Trump," Cruz said this morning.
* When Bernie Sanders first started running for president last year, he said practically nothing about Hillary Clinton during his speeches. As Sanders has grown far more competitive, that's changed.
* While tomorrow's presidential primaries will receive the bulk of the attention, there are some down-ballot races of interest, too. Among the contests to keep an eye on are the Democratic U.S. Senate primary in Illinois, the Republican U.S. House primary in John Boehner's Ohio district, and primary challenges to Sen. Richard Burr (R-N.C.) and Rep. John Shimkus (R-Ill.).
* Sen. Ron Johnson (R-Wis.), displaying rattled confidence, has spent years posting his radio interviews to YouTube. Last week, the Republican senator, worried about re-election, "made them inaccessible."
* And in a rather enthusiastic endorsement, the editors of National Review, a prominent conservative magazine, officially threw their support to Ted Cruz in the new issue.
