The Trail

The Obama campaign alerted about 65,000 supporters on Monday that they would receive tickets to the open-air event. But the combination of history, an unprecedented grass-roots campaign and unseasonably warm weather is causing Chicago authorities to brace for hundreds of thousands more in the parks and boulevards nearby.

As foreign television correspondents framed their live shots against Chicago monuments on a 71-degree afternoon, three young women shouted happily to passersby, "Who you going to vote for?"

Whenever someone called back "Obama!" they laughed and cheered.

At the same time, the prospect of a big crowd is creating worries about security. Acknowledging a sporadic history of hooliganism at music festivals and other events, Chicago Police Superintendent Jody Weis intoned, "We can't have mischief." Weis canceled days off for all Chicago officers.

No alcohol will be served inside the fence that will encircle the ticketed supporters -- only hot chocolate, a menu choice made long before anyone saw that lemonade might be a more appetizing beverage on what is expected to be a balmy night.

The gates to the rally enclosure will open at 8:30 Central time, with Obama certain not to appear before the West Coast polls close at 10 p.m. Central and perhaps much later.

One sign of the security concerns that accompany the Illinois Democrat wherever he goes is the bulletproof glass panels installed at each end of the stage from which he will address the crowd and the nation.

OBAMA'S LATE FUNDRAISING

Big Checks, Big Haul

Over the past two weeks, Barack Obama's campaign has raised $11 million in donations of $1,000 or greater, according to filings with the Federal Election Commission.

That $11 million figure doesn't include all the small contributions generated by e-mail solicitations, which had the potential to raise tens of millions more for Obama to spend during the final days of the campaign. How much money arrived in smaller donations won't be reported until after the election, as the FEC requires candidates to report only contributions of $1,000 or more during the final 20 days of the campaign.

One interesting tidbit emerged from the reports: On Oct. 29 and 30, during the 48-hour period surrounding Obama's half-hour infomercial, the campaign reported having collected more than $1.2 million in checks of at least $1,000.
