Why is Obama still using racial issues just before Tuesday?

Republicans are running ads against (R)Justin Amash saying he "Voted With Obama 51% of the Time" What do you think of these ads?

• https://www.weeklystandard.com/blogs/ad-amash-voted-obama-51-percent-time_786685.html A new ad from a Republican primary challenger to Michigan congressman Justin Amash notes he has voted for bills supported by Barack Obama more than any other Republican in Congress. Brian Ellis, a businessman from Grand Rapids, released the 30-second ad on Tuesday. "Amash was the only Michigan Republican to vote against a balanced budget amendment, and Amash voted against banning gender selection abortions," says the voiceover. "The fact is, Justin Amash voted with President Obama 51 percent of the time." Amash, a libertarian, was first elected to the House in 2010, but his tendency to vote against his party has earned him frustration and scorn from his fellow Republicans. He has received opposition from Republicans on one of his biggest issues, defunding the National Security Agency's terrorist surveillance program. The primary in Michigan will be August 5.
