Tune in Sunday

Lincoln Diaz-Balart and challenger Raul Martinez will go head to head Sunday on Univision's Al Punto. Univision promises the two will discuss the economy, U.S. policy towards Cuba and Latin America, "pre-conditions for meeting with rogue states, and why they should be elected to the US Congress."

The show will also feature a candidate running for another office: Republican presidential contender John McCain. The show says host Jorge Ramos asks McCain "about the increasingly negative tone his campaign has taken this past week" and that in a "candid exchange, Senator McCain explains why he thinks Democratic presidential candidate Barack Obama is dangerous for the country, what his foreign and military policy would be towards Venezuela, his plan for immigration reform, what role the Latino vote will play come November, and why he thinks the U.S. was justified in going to war in Iraq.

The show airs at 10 a.m.
