Democratic presidential candidate John Edwards is now being targeted by his rivals. Howard Dean attacks Edwards and others who he calls “Washington candidates” in a TV ad. And Dick Gephardt today attacked Edwards’ views on trade. Edwards says he’s seen the size of his crowds in Iowa grow — in part — because of those kind of attacks. Edwards says people are tiring of the “petty sniping” the other candidates are engaging in. He also says undecided voters are starting to make up their minds and are looking seriously at him. Edwards says his events are attracting overflow crowds, with he calls “amazing.” While rivals have been touting out-of-state organizers who’ve come to Iowa to turn out the vote on Monday, Edwards says he’s counting on Iowans who support him to help spread the word about his candidacy and get like-minded folks to the Caucuses. Massachusetts Senator John Kerry’s been campaigning in eastern Iowa today, accusing the Bush Administration of setting up an “economy of special privilege” for wealthy and powerful Americans. Kerry stressed his commitment to repealing the Bush tax cut for the wealthy, while maintaining the tax cuts for middle and lower income Americans.
