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:
* In Kentucky's U.S. Senate race, the new NBC/Marist poll found Senate Minority Leader Mitch McConnell (R) with a surprisingly large, eight-point advantage over Alison Lundergan Grimes (D), 47% to 39%. Nearly all other recent polling shows McConnell with a much smaller lead.
* In Colorado's U.S. Senate race, the new NBC/Marist poll shows incumbent Sen. Mark Udall (D) with a six-point lead over Rep. Cory Garnder (R), 48% to 42%.
* In Arkansas' U.S. Senate race, the new NBC/Marist poll has Rep. Tom Cotton (R) leading incumbent Sen. Mark Pryor (D), 45% to 40%.
* In Iowa's U.S. Senate race, a brand new Loras College poll shows Rep. Bruce Braley (D) with a five-point lead over state Sen. Joni Ernst (R), 45% to 40%.
* As of late last week, no one had any idea who was running Sen. Pat Roberts' (R) re-election campaign in Kansas. Over the weekend, Republican operative Corry Bliss took over "day-to-day operations" of the team. The election is eight weeks from tomorrow.
* A Louisiana judge on Friday threw out a residency challenge to Sen. Mary Landrieu's (D) re-election campaign. The suit had been filed by a Republican state representative.
* Texas State Sen. Wendy Davis (D), her party's gubernatorial hopeful, "breaks what is still a major taboo in her forthcoming memoir by telling her abortion stories -- one an ectopic pregnancy, another a severe fetal anomaly."
* Former Sen. Scott Brown (R-Mass.), running this year in New Hampshire, is now trying to deny he was ever a "lobbyist." Rather, the Republican simply did government-affairs work for a lobbying firm (which, for all intents and purposes, means he was a lobbyist).
* And on a related note, how diligent are American Bridge's trackers? Apparently, this diligent: "Scott Brown went canoeing in New Hampshire on Friday afternoon, and a tracker with a video camera followed behind -- in a kayak. 'Wherever Scott Brown goes, so goes American Bridge,' said Gwen Rocco, the left-leaning research group's communications director."
