The latest from the Political Grapevine:

Police Protest

Despite being awarded a pay raise, Boston police officers plan to picket 29 state welcome parties on the eve of the Democratic National Convention — and several delegations unwilling to cross the picket lines say they'll boycott the events.

Boston Mayor Thomas Menino says that with a new contract in the works, police have no reason to picket — but union officials say they're protesting on behalf of other unions without contracts. Delegations from Michigan and Ohio have already cancelled their welcome parties, and Maryland Democrats say they won't cross picket lines to attend a Sunday night reception hosted by the city.

Corzine Says ‘Stay Home’

In further convention news, New Jersey Sen. Jon Corzine, who also serves as chairman of the Democratic Senatorial Campaign Committee, is telling Democratic candidates to skip the Convention next week.

Corzine says they should be at home — "dialing for dollars and shaking hands." And the chairman of Democratic Campaign Committee in the House, Robert Matsui of California says he's telling candidates — "It's not even a close question. They should be home, making phone calls," adding — "I've never seen a candidate make money" at a convention.

More on Moore

Earlier this week we told you that singer Linda Ronstadt was booed during a performance — and escorted out of the Aladdin casino in Las Vegas — for calling Michael Moore a "great American Patriot." Now, the casino's prospective new owner has invited Ronstadt back to the Aladdin for a second show — and he's asked her to bring Moore along for the performance.

Meanwhile, Ronstadt repeated her praise of filmmaker Moore at a Livermore, California concert on Thursday. The Contra Costa Times reports everything was just fine until she dedicated the encore to Moore ... which was met with cheers, scattered boos, and over a hundred walkouts. The song, by the way, was "Desperado."

Patriotic Price

Finally, an anonymous independent presidential hopeful has taken his search for a running mate to eBay. The unnamed candidate from Massachusetts, who supports universal health care and a minimum wage hike — and who says if elected, he would bring his four pet goats to the White House Lawn — is auctioning off the position as his running mate to eBay bidders. Bidding starts at a patriotic $17.76.
