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.

* In a surprising move, Rep. Adam Putnam (R-Fla.), considered a rising star on the Hill, will give up his seat to run for Agriculture commissioner in Florida. Most believe Putnam hopes to use the position as a stepping stone for a gubernatorial campaign.

* In New York’s vacant House seat, Democrats have chosen venture capitalist Scott Murphy to run to replace Sen. Kirsten Gillibrand.

* Speaking of Gillibrand’s seat, new RNC Chairman Michael Steele has said the race in New York’s 20th congressional district is his first order of business. Steele said electing a Republican in a conservative, reliably-“red” district would send a “powerful signal to the rest of the country.”

* Not surprisingly, Jerry Brown wants, once again, to be governor of California.

* Sen. Chuck Schumer (D-N.Y.) is unlikely to face a credible Republican opponent next year.

* Should Illinois Sen. Roland Burris (D) seek a full term next year, his chances are mixed. A Research 2000 poll shows Burris leading Rep. Jan Schakowsky and State Treasurer Alexi Giannoulias in a Democratic primary (though “undecided” was easily the big winner), and leading likely GOP opponent Rep. Mark Kirk, 37% to 30%.

* Another Research 2000 poll showed no clear frontrunner in Florida’s 2010 Senate race, with most of the major candidates lacking strong statewide name recognition.

* Rep. Todd Tiahrt (R-Kan.) kicked off his 2010 Senate campaign over the weekend.

* Is retired football player Franco Harris considering a Senate campaign? It’s possible.
