Washington (CNN)– It is one of the most influential voting blocks and key to the 2012 presidential election, but President Obama's popularity continues to decline among Hispanic and Latino voters and now the president is facing criticism for once again skipping a major Latino convention.

The annual conference of NALEO, The National Association of Latino Elected and Appointed Officials, is being held this weekend inSan Antonio,Texas. For the third year in a row, the president declined to speak at the conference. The White House says it's simply a scheduling issue and the president cannot make it to every conference he would like to attend.
