Tomorrow, Pennsylvanians go to the polls. For weeks Hillary Clinton and Barack Obama have been courting the Keystone state nonstop. The candidates have bowled, and traded bitter barbs on everything from patriotism, Iraq, small town America, and each other’s character.

We are all about Pennsylvania today, too — bringing Pennsylvanians to the microphone to tell us what they’ve learned about politicking and about the candidates who would lead the nation.

This hour On Point: Pennsylvanians tell all the day before the primary.

Between the war and the economy, it looked like a slam-dunk year for Democrats and the White House. It may still be.

But the long-slog trench warfare between Hillary Clinton and Barack Obama has some Democrats scared that it’s slipping away. That John McCain is making hay while the Dems duke it out.

Bill Clinton now says, “Chill out.” Everything will be fine. Not everyone’s so sure.

This hour, On Point: to chill out or freak out — Democrats weigh the truth and consequences of a long, long primary campaign.

Hey, stop the presses. New Hampshire has written its own headline. Upset! Comeback! It’s Clinton over Obama — never mind Iowa and the polls and the magic. It’s McCain over Romney — never mind, again, the money of the man who was governor right next door.

Hillary Clinton never quit and nearly cried and pulled it out in New Hampshire. John McCain came back from the political dead zone to smack Mitt Romney.

But the way ahead is still a mystery in both parties — you might say now more than ever.

This hour, On Point: What happened in New Hampshire. And what now?

New Hampshire was supposed to be a firewall for the Hillary Clinton campaign — the primary stronghold where she would anchor her drive for the White House. Instead, it’s primary day and New Hampshire is a major challenge.

The other kid from Chicago, Barack Obama, has a solid lead in opinion polls. John Edwards is nipping at her heels. And the chemistry and expectations of the Democratic Party are in full flux as voters head to the polls.

Nobody’s conceding. It’s a fight that goes deep. And we are in New Hampshire, right in the middle of it.

This hour, On Point: the Democrats, and the battle for the party and the nation’s first primary.

Iowa got the first caucuses, but New Hampshire holds the first primary. Today, on a beautiful day in the snowy Granite State, the pressure is on and the stakes are huge for both Republican and Democratic presidential contenders.

Hillary Clinton emoted yesterday as polls showed Barack Obama in the lead. John McCain looks strong as Mitt Romney struggles for a first win. Independents may hold the key.

We are in New Hampshire today, in the thick of both parties’ action — first, the Republicans.

This hour, On Point: McCain, Romney, Huckabee, and the GOP race for victory in New Hampshire.

Only four days after the first votes, in Iowa, of Election ‘08, and one day before the New Hampshire primaries, Americans are in the thick of one of the most amazing political seasons in years.

But one thing’s been missing: the late-night laughs. Leno and Letterman sneaked back on last week. Tonight, Jon Stewart and Stephen Colbert return but without their striking writers.

Not to worry. We’ve got ‘em.

This hour, On Point: striking late night humor writers from The Daily Show and Colbert Report, on their battle, the New Hampshire race, and the zingers we’re missing without their wit.
