ABC News’ Jennifer Parker Reports: Continuing his attack on Republican frontrunner Sen. John McCain, conservative radio show host Rush Limbaugh devoted a significant portion of his radio show Monday to urging conservatives not to vote for the senator in tomorrow’s Super Tuesday contests.
For weeks, Limbaugh has been on the attack against McCain, branding the Arizona senator a "liberal" and suggesting he would destroy the Republican Party.
On his radio show Monday Limbaugh said that if McCain is elected president, he would destroy the Republican party by working with Democrats to pass liberal legislation.

"He’s going to reach out to Democrats in Congress," Limbaugh said, citing "McCain -Kennedy" and "McCain -Feingold" as examples of McCain-sponsored bipartisan legislation.
"This is how he’s going to get even with Republicans for defeating him in South Carolina in 2000," Limbaugh said.
"The Republican Congress will effectively be neutered."
In 2000, McCain lost South Carolina to George W. Bush, effectively killing his first presidential bid.
Limbaugh also suggested conservatives should be wary of media endorsements of McCain. McCain has won the endorsement of the New York Times.
"It was just six months ago that if a candidate was endorsed by the liberal media we were instantly suspicious of them," Limbaugh said.
Now he said, "we’ve got drive-by media organizations having orgasms about McCain."
The conservative radio host also lambasted Fred Barnes, editor of the conservative magazine The Weekly Standard for an editorial titled "Let’s Grow Up Conservatives" that urges conservatives to give McCain a chance if he continues to reach out to them.
"Fred, you used to be one of us!" Limbaugh said. "Now you seem to be all for Republicans having its liberal wing too."
Limbaugh also suggested McCain is winning over anti-abortion advocates, despite McCain’s long-held record of opposing abortion rights.
"It’s pro-choicers who are voting for McCain. That’s who liberals are!" Limbaugh said.
McCain’s chief Republican rival former Gov. Mitt Romney aired a campaign ad today on Limbaugh’s radio program attacking McCain’s record on taxes and immigration.
"John McCain, he’s been in Washington a long time," the announcer says.
While Limbaugh has not endorsed Romney, he has been urging his listeners for weeks not to vote for McCain at a time when McCain and Romney have argued over who is the true conservative.
While Romney has argued that he is a "Ronald Reagan" conservative, many of his earlier positions on abortion, same-sex marriage and gun rights while he was governor of Massachusetts leave many conservatives doubtful of his candidacy.
McCain, meanwhile, has always had a difficult relationship with the conservative wing of the Republican party.
Before the South Carolina primary, McCain’s 95-year-old mother, Roberta, urged conservative to "hold their nose" and vote for her son.
Limbaugh’s opinions appeared to rub off on one caller Monday named Bruce.
"I’m not a mind-numb robot and I’m not going to vote for John McCain!" the caller said.
Limbaugh’s outspoken rejection of McCain led former Republican Senate leader Bob Dole to write him a letter today that was sent to media today by the McCain campaign.
"Rush," Dole wrote, "I was the Republican Leader from January 1985 until I left the Senate voluntarily in June 1996. I worked closely with Senator McCain when he came to the Senate in 1987 until I departed. I cannot recall a single instance when he did not support the Party on critical votes.
“Whoever wins the Republican nomination will need your enthusiastic support. Two terms for the Clintons are enough,” Dole wrote.
