It's unfortunate he got attacked. But this was a liberal-on-liberal crime - Scalise is NOT a "conservative" in any real sense. Last year, he teamed up with the "congressional black caucus" to BAN the Confederate flag in Virginia war cemeteries:
>Scalise, GOP House leaders vote to ban Confederate flags on VA cemetery flagpoles
>May 19, 2016 at 1:46 PM
>The House voted Thursday (May 19) to ban the display of the Confederate flag on flagpoles at federal veterans' cemeteries.
>The 265-159 vote would block descendants and others seeking to commemorate veterans of the Confederate States of America from flying the Confederate Battle Flag over mass graves on the two days a year that flag displays are permitted.
>California Democrat Jared Huffman drafted the prohibition, saying the flag represents "racism, slavery and division."
