Playing the race card is amounts to conceding the argument. However I do find it amusing to see the roles reversed. Doctor Ben Carson is the dying gasps of his campaign has played the race card on Dim Won, b/k/a Barrack Obama:
Washington (CNN )Ben Carson suggested that if elected president he might be the first African-American to hold the position noting, President Barack Obama was “raised white” and outside of the United States.
“He’s an ‘African’ American. He was, you know, raised white. Many of his formative years were spent in Indonesia. So, for him to, you know, claim that, you know, he identifies with the experience of black Americans, I think, is a bit of a stretch,” the retired neurosurgeon told Politico’s Glenn Thrush on his “Off Message” podcast aired Tuesday.
Rather playing the race card, Doctor Ben should have played the stupid card. Speaking of the stupid card, MSNBC is arguing the Ted Cruz and Marco Rubio are somehow not Hispanic, from Newsbusters: 
As if they didn’t learn anything from MSNBC’s Chris Matthews, the panel on Monday’s Nightly Show decided to call into question the Hispanic credentials of Republican presidential candidates Ted Cruz and Marco Rubio
Score one for Doctor Ben.
