MONDAY’S CAMPAIGN ROUND-UP…. Today’s installment of campaign-related news items that wouldn’t generate a post of their own, but may be of interest to political observers.

* New York’s gubernatorial race got a little more interesting last week, but Steve Levy’s Republican campaign is off to a rough start — a new Siena poll (pdf) shows him trailing former Rep. Rick Lazio in a GOP primary by 47 points. State Attorney General Andrew Cuomo (D) leads both Republicans by wide margins.

* Speaking of New York, now that Rep Michael Arcuri (D) voted with far-right Republicans against health care reform, after having voted for it in November, his union support in the district is poised to disappear entirely.

* In Kentucky, the latest Research 2000 poll shows right-wing ophthalmologist Rand Paul leading Kentucky Secretary of State Trey Grayson by 12 — 40% to 28% — in the Republicans’ Senate primary. In the Democratic primary, Lt. Gov. Dan Mongiardo leads state Attorney General Jack Conway by a slightly larger margin. In general election match-ups, both Republicans lead both Democrats.

* Michigan’s competitive gubernatorial race continues to be very close. A new Marketing Resource Group poll shows a three-way tie for the GOP nomination between Pete Hoekstra, Mike Cox, and Rick Snyder. Andy Dillon leads the Democratic field.

* North Dakota Republicans met at a convention and chose state Rep. Rick Berg to take on Rep. Earl Pomeroy (D) in November.

* Former Obama campaign aide Steve Hildebrand was prepared to take on Rep. Stephanie Herseth Sandlin (D-S.D.) in a Democratic primary if she voted against health care reform. She opposed the bill, but Hildebrand has apparently changed his mind.

* Sen. George LeMieux (R-Fla.) was appointed as a place-holder senator, but apparently he’s thinking about running for his own term at some point.

* And in California, Gov. Arnold Schwarzenegger (R) now has the worst poll numbers of “any governor in modern state history including Gray Davis, who was ousted by Schwarzenegger in a popular uprising.” The former actor’s approval rating in the latest Field Poll was 23%.
