Former Republican Congressman Joe Walsh warned his fellow party members on Thursday that they would “get wiped out in 2020” if they failed to denounce the racism seen at Trump rallies. Walsh told CNN’s Brianna Keilar that Trump voters who chanted “send her back” to Democratic Rep. Ilhan Omar (D-MN) are full of “hatred.” “It’s ugly, it’s racist, it’s anti-American, and it ought to be denounced,” Walsh said.
