And the phones are ringing - so much so that the city has hired three temporary employees to field phone calls.
"This morning, the phones were ringing off the hook, and people weren't able to get through," Anderson spokesman Patrick Thronson said Monday afternoon. "We're also setting up a separate voice-mail box to record messages if the lines [to the temps] are busy."
The GOP is angry Anderson is helping organize and will be speaking at an anti-Bush rally Wednesday. The president is coming to Utah this week to speak to the American Legion's national convention.
The party paid to send out voice messages and air radio ads to decry the "negative, disrespectful and embarrassing image" Anderson is sending about Utah, according to a news release.
Thronson said the calls haven't changed Anderson's mind. "The mayor's still speaking on Wednesday."
Here is a copy of the radio ad text, according to a GOP news release:
"America is at war against an enemy determined to strike us at home. Just days ago terrorists were caught planning to blow up flights to America. The threat to our country is real. And the choice is clear.
"Do we do whatever it takes to win the war on terror? Or do we embolden the terrorists with a cut-and-run strategy? Mayor Rocky Anderson has made his decision. He's invited professional protester Cindy Sheehan to Utah to convince you that America should retreat.
"Cindy Sheehan called Al-Qaeda in Iraq 'freedom fighters.' And she called America 'the largest terrorist organization in the world.' Said she'd rather live under dictator Hugo Chavez [Venezuela's president] than President Bush.
"Now Rocky Anderson has invited her to Utah. Does he really share her anti-American beliefs?
"President Bush is visiting Utah to pay his respects to our nation's veterans.
"Call Rocky and tell him to stop embarrassing Utah: 801-535-7704.
That's 535-7704.
"Paid for by the Utah Republican Party."
