(CNN) - Voters across the country go to the polls Tuesday night for
Here are three things to watch.
1) Can you buy an election?
Of course not - that's against the law. But two wealthy Floridians are pouring part of their personal fortunes into primaries: Billionaire real estate investor Jeff Greene hopes to grab the Democratic U.S. Senate nomination from U.S. Rep. Kendrick Meek and millionaire former health care executive Rick Scott is running against Bill McCollum, the state's attorney general.
Three other largely self-funded candidates have already secured a place in the November general election with scads of their own money: Linda McMahon, whose family built World Wrestling Entertainment into a multibillion-dollar business, is the GOP nominee for the U.S. Senate in Connecticut. Meg Whitman, former eBay president and CEO, is the GOP nominee for governor in California. And Carly Fiorina, former Hewlett-Packard CEO and AT&T executive, is the GOP nominee for U.S. Senate in California.
(CNN) - Former President Bill Clinton said he sees parallels in the mood of the country now and on April 19, 1995, when the bombing of a federal building in Oklahoma City killed 168 people while he was in the White House.
"There's the same kind of economic and social upheaval now," the former president told CNN's Wolf Blitzer in an interview to air on Friday on "The Situation Room."
"Then you had the rise of extremist voices on talk radio. Here you have a billion Internet sites," Clinton said.
And while the hard-core, anti-government radicals are still a minority, "they can communicate with each other much faster and much better than they did before. The main thing that bothered us since the time of Oklahoma City was that already there was enough use of the Internet that if you knew how to find a Web site - and not everybody even had a computer back then, but if you knew how to find it, you could learn, for example, how to make a bomb."
"Now everybody has got a computer, Web sites are easily accessible. And you can be highly selective and spend all of your time with people that are, you know, kind of out there with you," he continued.
ST. PAUL, Minnesota (CNN) - Two protesters tried to disrupt Republican presidential nominee John McCain's speech behind and to the right of the podium.
One took off an outer garment to reveal a pink garment underneath and held a banner in front of her.
The banner was snatched away by a man nearby who threw it to the floor and the protester tried to pick it up and struggled with several people for it.
One of the protesters flashed a peace sign while being led away by a single man. The other struggled with several men before being carried up the stairs and out of the auditorium.

The question is whether the win came soon enough.
Barack Obama's loss in another big state and the margins by which he lost among blue-collar and rural voters on Tuesday, on the other hand, may raise questions about his electability.
Some polls had shown Clinton with a double-digit lead in Pennsylvania. But in the weeks between the last primaries in Ohio and Texas, Obama had whittled down Clinton's advantage.
