Today’s installment of campaign-related news items from across the country.

* After legal efforts to block the event came up short, Republican megadonor Elon Musk held a rally of sorts in Wisconsin on Sunday, ahead of Tuesday’s state Supreme Court election, and he rewarded a pair of apparent supporters with $1 million checks. Brad Schimel, the conservative candidate in the race, was not in attendance.

* On a related note, Musk also told Wisconsin voters over the weekend that the state Supreme Court election could determine “the future of America and Western Civilization.” He added that he believes the race is likely to “affect the entire destiny of humanity.”

* In Louisiana, Republican Gov. Jeff Landry hoped voters would approve a series of proposed changes to the state Constitution, but they lost by wide margins.

* While much of the attention in the April 1 elections has focused on the Wisconsin Supreme Court election and the congressional special elections in Florida, Bolts’ Daniel Nichanian highlighted some of the down-ballot contests that election waters will be keeping an eye on.

* In Florida, Republican Gov. Ron DeSantis’ wife, Casey DeSantis, hasn’t yet announced a gubernatorial race of her own, but NBC News reported that taxpayer-funded staffers in the governor’s office “have been making fundraising calls to state lobbyists, asking them to commit to raise money” for a DeSantis-aligned political committee that would support the first lady’s potential candidacy.

* And in Texas, where it’s been three weeks since the late Rep. Sylvester Turner’s passing, there are a variety of candidates who’ve kicked off campaigns to succeed him. It falls to Gov. Greg Abbott, however, to schedule a special election, and so far, the Republican not only hasn’t called such a race, he also hasn’t said when he’d get around to making such a decision.
