Mark Halperin’s three things to watch for in presidential politics for Thursday, September 11:
1) Watch Bill Clinton and Barack Obama, who are having lunch in Harlem this afternoon. The former president made the invitation, knowing Senator Obama was planning to be in New York today for 9/11-related events. Watch to see what we learn about what Bill Clinton says to Barack Obama about how he might begin to fight back against these Republican attacks that have discombobulated the Democratic campaign.
2) Watch ABC’s Charles Gibson interview with Sarah Palin in Alaska. This will be Palin’s first meaty television interview since she was put on the Republican ticket. The first part of the two-day interview will air tonight at 6:30 pm ET on “World News.” The interview will also form the basis of a special prime-time edition of “20/20″ Friday. Pay attention to what comes out of that interview.
3) Watch Service Nation, a forum on national service hosted by TIME magazine and CNN, featuring both John McCain and Barack Obama. The forum will kick off tonight at about 8:00pm ET at Columbia University in New York, on a day when both campaigns have agreed to call off their attacks to mark the anniversary. TIME managing editor Rick Stengel and PBS NewsHour anchor Judy Woodruff will question the candidates— watch to see what happens at that very important event.
