The vast, right-wing conspiracy is back, baby!

Once derided for her use of that phrase - which she used to describe the actions of Republicans against her husband during the Monica Lewinsky scandal - presidential candidate Hillary Rodham Clinton is now using it to her advantage.

Or at least trying to. Speaking Tuesday to Democratic municipal officials in Nashua, N.H., the New York senator used the term to hammer the GOP on election irregularities.

She also used the phrase similarly during a campaign appearance over the weekend in New Hampshire, bringing back memories of 1998-1999.

As a mountain of evidence of Bill Clinton’s affair eventually came to be public knowledge, Hillary Clinton’s adamant denials were ridiculed.

At the same time, many Democrats have since insisted that Clinton was correct, pointing to the well-documented efforts by conservative financier Richard Mellon Scaife to fund a network of anti-Clinton investigations.

On Tuesday, the Democratic frontrunner asserted the conspiracy is alive and well - citing as proof the 2002 case of Election Day phone jamming in New Hampshire.

In that case, two Republican operatives pleaded guilty to criminal charges, and a third was later convicted.

“To the New Hampshire Democratic party’s credit, they sued and the trail led all the way to the Republican National Committee,” Clinton said.

“So if anybody tells you there is no vast right-wing conspiracy, tell them that New Hampshire has proven it in court.”

According to CNN, Clinton accused the GOP of a number of other anti-voter actions Monday, including intimidating phone calls during the contentious 2006 midterm elections.

New Hampshire Democratic Party chairwoman Kathy Sullivan said she agreed completely with the senator’s description of the case.

“They are the most disgusting group of political thugs that I have ever seen,” she said of the GOP groups perpetrating the fraud.

Clinton made her charge of conspiracy in response to a question about her proposed bill that would make Election Day a federal holiday, as well as making it a crime to send misleading or fraudulent information to voters.

She also said the government should do more to end unusually long lines at certain polling places, an issue Bill Clinton has also raised.

“It just so happens that many of those places where people are waiting for hours are places where people of color are voting or young people are voting. That is un-American, and we’re going to end it,” Clinton said.
