The New York Senator shares some laughs with Jon Stewart before her big day

It’s the day before the biggest primary in her presidential campaign, and where did Hillary Clinton spend it? Hanging out with Jon Stewart on Comedy Central’s Daily Show Monday night.

“It is pretty pathetic,” Clinton joked via satellite from Austin, Texas. “It’s been a lot of fun. I wish you were out on the campaign trail with us … you could make fun of us in person rather than by remote.”

“I really prefer this,” Stewart replied. (See more from her appearance here.)

Clinton faces off Tuesday with Barack Obama in Texas, Ohio, Rhode Island and Vermont – in what political watchers have called a make-or-break moment for Clinton. On the Republican side, it’s a bit less dramatic, with Republican Sen. John McCain expected to grab enough delegates to win the GOP nomination.
