Yes, that's McCain sitting next to Rep. Kendrick Meek at an ACORN event. The very same ACORN his campaign now rails against and is accusing of trying to "steal" the election for Obama:

Miami Dade College press release:

Miami, Florida – February 20, 2006 ― Leaders from a diverse array of sectors will hold a rally in Miami on Thursday, February 23, 2006, in support of comprehensive immigration reform in an effort to keep immigration reform at the forefront of the public debate. Leaders from both political parties, immigrant communities, labor, business, and religious organizations will gather to call on Washington to enact workable reform.

The rally will feature Sen. John McCain (R-AZ) as the headline speaker along with elected officials, immigrants and key local and national leaders. Sen. McCain is one of the chief sponsors of the Secure America and Orderly Immigration Act; bipartisan, comprehensive immigration reform legislation introduced last Congress and scheduled for consideration by the Senate in the coming weeks. A similar rally with Sen. McCain is planned for New York City on February 27

The rally in Miami is being sponsored by the New American Opportunity campaign (NAOC) in partnership with ACORN, Catholic Legal Services - Archdiocese of Miami, Florida Immigrant Advocacy Center, Florida Immigrant Coalition, Miami Dade College, People for the American Way/Mi Familia Vota en Acción, Service Employees International Union, and UNITE HERE.

This campaign is one of a kind. Every time it settles on a line of attack, it always undermines it days later.
