Is the RNC illegally colluding with the White House while creating television advertisements that, among other lies, accuse Democrats of a lack of patriotism?

When President Bush laid out the potential threat that unconventional weapons posed in Saddam Hussein's hands last year in his State of the Union address last year, he became tongue-tied at an inopportune moment.

The line read, "It would take one vial, one canister, one crate, slipped into this country to bring a day of horror like none we have ever known." But Mr. Bush stumbled between the words "one" and "vial." And when at the word vial, he pronounced the "v" as if it were a "w."

Yet in a new Republican commercial that borrows excerpts from that speech, Mr. Bush delivers that line as smoothly as any other in the address, without a pause between "one" and "vial," and the v in "vial" sounds strong and sure.

Republican officials acknowledged yesterday that the change was a product of technology. The line, they said, was digitally enhanced in editing "to ensure the best clarity."

The difference between the speech and excerpt was noticed by strategists for former Gov. Howard Dean of Vermont. They saw it as they put together their own advertisement attacking the spot, which presents the Democratic candidates as undermining the fight against terrorism. Word trickled back to Democratic officials, who retrieved the tape and confirmed that there was, indeed, a difference.

The Democrats asked whether the Republican National Committee had gone to the White House with sound equipment to have Mr. Bush recite the line anew for what was the first Republican commercial of the campaign season here. That might have meant that the party was not being truthful when it said it had not coordinated with Mr. Bush when it made the advertisement, a possible violation of law.
