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.

* Roland Burris went to Capitol Hill this morning, and introduced himself to the media as the “junior Senator from the state of Illinois.” When he tried to join his “colleagues,” he was told that his “credentials are not in order,” and he would not be permitted onto the Senate floor.

* Though there were rumors that Harry Reid might consider seating Al Franken today, the Majority Leader backed off last night. The possibility of Franken being sworn in later this week, though, remains alive.

* Speaking of Franken, Norm Coleman’s Senate office was ordered closed yesterday, at the direction of Senate Rules Committee.

* If the latest survey from Public Policy Polling is right, Caroline Kennedy’s support has fallen sharply of late, and state Attorney General Andrew Cuomo is the public favorite to fill New York’s Senate vacancy.

* In related news, National Republican Senatorial Committee Chairman John Cornyn (R-Texas) will support Rep. Peter King’s (R) Senate campaign in 2010, which in turn should discourage a primary fight.

* Nothing’s official, but Jeb Bush’s Senate campaign in Florida is far from a lock, and there’s increasing speculation that he’ll skip the race.

* The prospect of a Chris Matthews Senate campaign in Pennsylvania appears increasingly unlikely.

* If Sarah Palin considers a Senate campaign in 2010, she may struggle against Sen. Lisa Murkowski (R) in a GOP primary.

* Meg Whitman appears to be gearing up for a gubernatorial campaign in California. She would presumably run as a Republican.
