In a conference call with reporters this morning, Wisconsin Gov. Jim Doyle and Massachusetts Sen. John Kerry hit McCain over comments he made last night at a townhall meeting in Greendale, Wisc., where they said he misled the audience on the number of troops currently in Iraq. The two Obama supporters also charged McCain with "crossing the line," when he used a picture of himself and Gen. David Petraeus in a fundraising e-mail.

"When Senator McCain comes into Wisconsin and makes statements saying that they have drawn down to pre-surge levels, that is just not true," Doyle said. "I assume Senator McCain just doesn't know the facts here. ... The fact is we are not down to pre-surge levels."

"I'm also very concerned about the e-mail that has gone out as well from Senator McCain where he has put General Petraeus in uniform right into an email fundraising message," Doyle continued. "That's the kind of politicization of the military that we have worked so hard not to have happen here."

Kerry questioned McCain's ability to make a judgment on troop levels if he is elected president. "The top military leaders of our country have continually said in recent testimony before the Congress that our military is over-extended in Iraq and that we cannot sustain the current levels," Kerry said. "That is to be contrasted with the Republican nominee-presumptive, John McCain, who appears not to know the levels of the troops and adamantly continues to propose keeping them overextended."

"If you don't know the numbers of troops, it's very difficult to make a judgment about whether or not they're overextended. It's also very difficult to have an understanding as a citizen about what level of troops he's going to keep there."

On the fundraising e-mail, Kerry said: "The Republicans have grown very skilled over the years at using our troops as props...but not providing a policy that is up to scale with the level of troop sacrifice."

UPDATE: McCain spokesman Tucker Bounds responds to the statements by Kerry and Doyle:

"Clearly John Kerry and Barack Obama have very little understanding of troop levels, but considering Barack Obama hasn't been to Iraq in 873 days and has never had a one on one meeting with General Petraeus, it isn't a surprise to anyone that he demonstrates weak leadership. What informed people understand, John McCain included, is that American troops are not even close to Surge levels.

Three of the five Army 'Surge' brigades have been withdrawn and additional Marines that were initially deployed for the 'Surge' have come home as well -- the remaining two brigades will be home in July. Talk about a political stunt, it's sending out campaign surrogates to parse words about a topic Barack Obama has no experience with, and has shown zero interest in learning about."
