TUESDAY’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.

* At this point, the Democratic establishment continues to support Richard Blumenthal’s Senate campaign in Connecticut. That should help his chances, barring any additional revelations.

* Kentucky Secretary of State Trey Grayson has a theory to explain why he’s losing to right-wing ophthalmologist Rand Paul in the Republican Senate primary: Paul is on Fox News all the time, getting softball questions, and Grayson isn’t.

* It seems implausible, but Sen. Bob Bennett (R), defeated at the Utah Republican Party’s convention and ineligible for the primary ballot, continues to drop hints about a possible write-in campaign.

* Speaking of Utah, Sen. Orrin Hatch (R) has heard rumors about facing a primary challenge, but he’s committed to running for re-election in 2012 anyway.

* Scott Walker, a Republican gubernatorial hopeful in Wisconsin, criticized Arizona’s scandalous immigration law on Friday, saying, “In America, we don’t want our citizens getting pulled over because of how they look.” Less than a half-day later, Walker announced his support for Arizona’s law. By Saturday, he announced he would have signed the Arizona measure into law.

* It seems all but certain that New York Attorney General Andrew Cuomo (D) will run for governor this year, but he won’t announce before the state Democratic Party convention begins in about a week.

* And Greg Sargent had a very smart piece yesterday about the primary campaigns of Bill Halter and Joe Sestak, who, if successful, really would represent a victory for the left.
