Tuesday will be one of the busiest political days so far this year because it's a "Super Tuesday" of midterm primary elections.
Voters in four states head to the polls, and the races are tight. Establishment candidates from both parties could be in trouble.
What do Tuesday's primaries say about voter discontent? Dr. Charles Dunn, dean of Regent University's School of Government, answered that question and more on the CBN Newschannel's Midday program. Click play for his comments.
Some of the hottest contests for Democrats are in Pennsylvania, where veteran Republican-turned Democrat Sen. Arlen Specter has a fierce challenge from Congressman Joe Sestak, a former Navy Seal.

Sestak has portrayed Specter as a senator with Republican ties who is more interested in his own job than the jobs of others.
"You don't vote for a change, you fight for a change," Sestak said.
"I'm trying to keep my job to save thousands of jobs in Pennsylvania," Specter said.
The two are running neck and neck, even though Specter is backed by President Obama.
In western Pennsylvania's 12th House District, voters will decide who should fill the shoes of the late Congressman John Murtha, who was a close ally with House Speaker Nancy Pelosi, D-Calif.
Republican businessman Tim Burns is trying to tie his Democratic opponent to Pelosi to win a seat that Democrats have held for decades.
Meanwhile, Democrat Mark Critz, who is a former aide to Murtha, is appealing to seniors in Pennsylvania who are worried about social security.
Critz is a rare Democrat: pro-life, pro-gun and opposed to Obama's health care plan.
GOP in Kentucky
The biggest Republican contest is in Kentucky, where Tea Party favorite Rand Paul is taking on Secretary of State Trey Grayson, who is the choice of Senate Minority Leader Mitch McConnell.
A victory by Paul, who is an eye doctor and the son of Presidential candidate Ron Paul, would be a blow to the Republican Party old guard.
In Arkansas, Sen. Blanche Lincoln is another Democratic incumbent in trouble. She's being challenged from the left by Lt. Gov. Bill Halter.
Oregon is the fourth state with contests on Tuesday. The two big races are for senator and governor in a state that votes by mail.
