Since Rep. Paul Ryan, R-Wis., came on the scene Saturday, Mitt Romney's rallies have felt different. The crowds are bigger. The audience is more raucous. Lines that used to be a routine part of the Republican presidential candidate's stump speech have become rousing battle cries.

At the NASCAR Technical Institute in Mooresville, N.C., 1,600 people crowded into the room and thousands more swarmed outside.

"I feel like I'm in Woodstock," gubernatorial candidate Pat McCrory exclaimed. "There's a parking jam!"

This week, the presidential campaign has been dominated by debate over the welfare law from the 1990s. It's just the latest example of how both sides are trying to use the Clinton years to their advantage — portraying them as a halcyon golden age.

While President Obama and Mitt Romney offer competing visions every day on the campaign trail, there's also a more superficial aspect to their campaigns.

And on the surface, Obama and Romney events feel completely different.

Take a recent summer night in Leesburg, Va. Dorothy Fontaine had been standing outside of a local high school since the sun was high in the sky.

When asked why she would spend that much time waiting, Fontaine replied: "It's the president of the United States! I mean, isn't it cool to go see the president of the United States?"

Republican Mitt Romney campaigned this weekend in a state that has not seen much of either presidential candidate. Nobody considers Indiana a toss-up in the presidential race.

But the Senate contest there is a different story. It's a very close race, and the result could determine which party controls the Senate next year. So Romney showed up at a barbecue shack in Evansville to give the conservative Republican candidate a boost.

'Help Me Elect This Guy'

President Obama's national security adviser visited China this week, just as Republican presidential candidate Mitt Romney was attacking the administration's approach to that country.

"The cheating must finally be brought to a stop," Romney said Tuesday in a speech to the Veterans of Foreign Wars in Reno, Nev. "The president hasn't done it and won't do it, and I will."

China is the world's largest economy after the United States. It is one of the most important — and complicated — foreign relationships the U.S. has.

Republican presidential candidate Mitt Romney speaks to the Veterans of Foreign Wars in Reno, Nev., on Tuesday. It's a sort of launching pad for a foreign trip that will take Romney to three countries over the next week: the United Kingdom, Israel and Poland.

Romney, a man with a lot of domestic policy experience, is now trying to demonstrate his proficiency with international affairs.

SCOTT SIMON, HOST:

American flags are flying at half-staff today over the White House, and elsewhere in the country. The shootings in Aurora have silenced politics as usual - at least, for the moment. The Romney and Obama campaigns have both pulled their TV ads from the air in Colorado, a state that had three top political advertising markets in the country this week. NPR's Ari Shapiro reports on a somber day on the campaign trail.

In politics, money talks. And money from gay and lesbian donors is talking louder than ever in this election cycle.

That's partly a result of President Obama endorsing same-sex marriage, and it's partly because Republicans are starting to see contributions as well.

That's a huge change from just a few decades ago.

It's a bit less likely now than a week ago that you'll hear people accuse the Supreme Court of being politicized.

That's because this week, the court ended its session with two controversial decisions — neither one of which was decided on the usual and predictable split between the five justices appointed by Republican presidents and the four appointed by Democrats.

But that doesn't make the court any less of a political animal.

In the days following President Obama's announcement that he supports same-sex marriage, anecdotal evidence suggested that the political position had a financial payoff.
