Obama has said that McCain doesn't want to debate the issues.. Obama decline this offer:

Under McCain’s plan, the candidates would have met once a week between June and the Democratic National Convention at the tail end of August. Though it left room for negotiation of details, the McCain camp suggested that the candidates appear together for 60 to 90 minutes at each meeting and take "blind questions" from members of an audience ranging from 200 to 400 people.

Via Dean.  But then again, McCain is running a Spanish language ad that is pretty much full of outright lies regarding Obama's immigration policy:

In that vein, Mickey Kaus reported Friday that McCain's campaign is now running a Spanish-language ad attacking Barack Obama for failing to support McCain's comprehensive immigration bill.  It's yet another McCain ad chock-full of egregious distortions.  What the ad doesn't mention:

• Obama (like McCain) voted twice to end Senate filibusters on that bill.

• Both filibusters were led by the Republicans, not Obama or the Democrats.

• McCain himself said in the primaries that if the same bill were to come up for a vote in the Senate today, he would no longer vote for it.

Even Karl Rove thinks that McCain's latest batch of ads are going too far.  Now that's when you know something is amiss:

Via VodkaPundit.  And what about Obama's "strong stand" on getting our troops out of Iraq?  Well... as it turns out, what he says in public, and what he talks to the Iraqi Government about are completely different:

WHILE campaigning in public for a speedy withdrawal of US troops from Iraq, Sen. Barack Obama has tried in private to persuade Iraqi leaders to delay an agreement on a draw-down of the American military presence.

According to Iraqi Foreign Minister Hoshyar Zebari, Obama made his demand for delay a key theme of his discussions with Iraqi leaders in Baghdad in July.

"He asked why we were not prepared to delay an agreement until after the US elections and the formation of a new administration in Washington," Zebari said in an interview.
...
Obama has made many contradictory statements with regard to Iraq. His latest position is that US combat troops should be out by 2010. Yet his effort to delay an agreement would make that withdrawal deadline impossible to meet.

Supposing he wins, Obama's administration wouldn't be fully operational before February - and naming a new ambassador to Baghdad and forming a new negotiation team might take longer still.

By then, Iraq will be in the throes of its own campaign season. Judging by the past two elections, forming a new coalition government may then take three months. So the Iraqi negotiating team might not be in place until next June.

Then, judging by how long the current talks have taken, restarting the process from scratch would leave the two sides needing at least six months to come up with a draft accord. That puts us at May 2010 for when the draft might be submitted to the Iraqi parliament - which might well need another six months to pass it into law.

Thus, the 2010 deadline fixed by Obama is a meaningless concept, thrown in as a sop to his anti-war base.

How can you tell a politician is lying?  Well... you know the answer to that question.
