Today's installment of campaign-related news items that won't necessarily generate a post of their own, but may be of interest to political observers:
* Mississippi state Sen. Chris McDaniel (R) is reportedly set to file his long-awaited challenge to his recent primary defeat to Sen. Thad Cochran (R). Though the challenge was expected a while ago, the paperwork will reportedly be submitted to the Mississippi Republican Executive Committee today.
* The latest NBC/WSJ/Marist poll shows Republicans with a narrow lead on the generic congressional ballot, 43% to 41%, despite their recent antics and failures.
* A Florida judge on Friday ordered the state legislature "to submit a redrawn congressional map within two weeks to replace ones for two districts that were ruled illegal. In the ruling, Judge Terry P. Lewis of Florida's Second Judicial Circuit held open the possibility of delaying the November elections."
* In Illinois, Republican gubernatorial hopeful Bruce Rauner "channeled at least part of his fortune into the Cayman Islands, a Caribbean paradise long criticized as a tax haven for American investors." Rauner and his campaign team have so far refused to release a full set of his most recent tax returns.
* In Massachusetts' gubernatorial race, the latest Boston Globe poll shows state Attorney General Martha Coakley (D) expanding her lead over Charlie Baker (R), 42% to 32%.
* In Montana, the Billings Gazette's editorial board is urging appointed Sen. John Walsh (D) to simply give up and stop seeking a full term this fall. Following his plagiarism controversy, the paper said quitting would be "the honorable course."
* And believe it or not, Mitt Romney, the twice failed presidential candidate, is apparently a sought-after guest for GOP candidates. The former one-term governor will campaign this month for Republicans in West Virginia, North Carolina, and Arkansas. In September, Romney will make campaign appearances in Colorado and Virginia. And in October, he's scheduled events in Iowa and New Hampshire. Note, of these seven states, Romney lost four of them.
