Margolies, a proud in-law, awaits Hillary Clinton's address

Somehow the rumor had spread that former U.S. Rep. Marjorie Margolies of Montgomery County would be introducing Hillary Clinton on Thursday night.

"Everybody is saying good luck with your speech," she said.

A nice thought, but not true. She is, however, the mother-in-law of the person introducing Hillary Clinton: Chelsea Clinton, who married Margolies' son Marc Mezvinsky in 2010.

Margolies, who cast the deciding vote in favor of Bill Clinton's 1993 budget, then was defeated in the next election, is busy enough this week. She's a delegate and is escorting an international group of students from her work teaching at the Fels Institute of Government at the University of Pennsylvania.

"I have kids coming in, all my children are coming in," she said.

She said she was not nervous for her daughter-in-law. "She's amazing. She'll do what needs to be done. I don't think she feels any pressure at all."

She said she is fully behind Clinton for president, who she added was as adoring a grandmother to Charlotte, 22 months, and Aidan, born June 19, as, well, herself.

"They are totally adorable, oh my God," she said. "They're so sweet with her. Charlotte is so excited to see her, it's 'Gamma, Gamma.' "

In a nation that's fiercely divided - Democrat and Republican, protester and police, rich and poor - Gaye Lub seeks to answer a particularly pertinent question:

What do we have in common?

On Tuesday, in the shadow of Independence Hall, she mounted an art installation, "This Unites US," that invites people to write down things that everyone needs, regardless of income, race, religion, or politics.

Love, one person wrote.

Children to rear, wrote another.

Acceptance.

Clean water.

Food.

Shelter.

Lub, who drove here from her home in Napa Valley, Calif., stopping first at the Republican National Convention in Cleveland, wants people to look beyond the headlines and consider their shared humanity.

Her project features big, stand-up collages that depict causes and events in recent American history. Citizens have power to shape the future, she said, but only if they decide to act on what binds them as human beings.

"It's a simple step to get a common solution," she said.

Disgusted after two students committed suicide at her son's high school in Ocean City, N.J., Greta Schwartz built a coffin and dragged it 90 miles to Trenton to state her case for addiction and mental-health reform.

"At first I thought it may be a little too morbid," Schwartz said. "But the more people I talked to who knew somebody who had taken their life or died from drug addiction, I thought that's what's morbid."

She had the casket at Dilworth Park on Tuesday for a rally highlighted by former Rhode Island Congressman Patrick Kennedy.

"I've been in recovery myself and struggled for a long time with addiction - and I still do," said Kennedy, who served in office from 1995-2011. "I'm blessed to have the support so that I can stay in recovery, and I want to make sure other people have that same support."

Meanwhile, Schwartz is running out of space on her casket to inscribe the names of people who have died due to mental illness.

"There's definitely over 100 names on here, because I had over 100 when I started out today," Schwartz said, sweat dripping from her brow. "And I've had a lot of people add names to it."

The temperature hit 97 degrees on day one of the convention, and it wasn't much cooler Tuesday.

And that means a lot of demand for drinking water.

Philadelphia spent $39,000 to buy 88 pallets - 152,064 bottles - for distribution to people who were outdoors in some convention-related capacity, the mayor's office said. That includes city personnel, demonstrators, and other members of the public.

The city already had six pallets on hand, plus another six from the Second Alarmers, a volunteer group, and eight from the Salvation Army.

Total pallets: 108, containing 186,624 bottles, the mayor's office said.

As of midday Tuesday, 59 of the 108 pallets had been distributed by the city's Office of Emergency Management. Six more pallets were scheduled for delivery Wednesday, and the city is ready to buy more if needed, the mayor's office said.

Even by late afternoon, delegates, journalists, and others were still huddled around some stalls at Reading Terminal Market in search of a late lunch.

Melissa Olson and Tharen Stillday, Bernie Sanders delegates from Minnesota, ordered drinks from Old City Coffee and reminisced over lunch at the Little Thai Market.

Olson said she had salmon curry because it was "something to get me through the rest of the afternoon."

The food at the Terminal was far better than the options at the Wells Fargo Center, said Stillday, who had to wait 40 minutes Monday night to buy a hotdog.

The women planned to return to the Terminal on Wednesday to try one of Tommy DiNic's famous sandwiches.

"I've seen . . . Guy Fieri . . . he was here," Stillday said, "and so was Anthony Bourdain."

Then Stillday thought about other Philadelphia recommendations she'd picked up on foodie TV shows.

Was the best cheesesteak, she wondered, "something Luke's?"

A little sign is causing a lot of commotion at the Wells Fargo Center.

It reads "All-Gender Bathroom." And it is placed over what had been the sign for one of the building's women's restrooms.

The recently unveiled gender-neutral bathroom piqued curiosities over the weekend when it was first spotted by members of the media. The renovations were minimal - basically, just the sign. Inside, there are a dozen blue stalls. And apparently just one other restroom in the center was similarly changed.

Convention-goers have been unfazed, with many beyond the convention's 27 transgender delegates using the restroom.

"It doesn't make me nervous at all," delegate Lula Dualeh told BuzzFeed News. "I just need to use the restroom. I don't care who's next to me."

Some conservatives aren't so comfortable with the coed quarters. Fox News pundit Tucker Carlson called the bathroom "disgusting."

"I mean, I guess we're liberated by this?" he said. "Everyone should come visit one and see the reality of it. It's unbelievable."

Another journalist questioned if the move was nothing more than a publicity stunt, given the restroom's proximity to the media booth.

To that, DNC spokesman Lee Whack declined to comment.
