And why not? Donald Trump is doing exactly what voters want him to do and have wanted Republican politicians to do for a long, long time. Making a serious effort to trim waste, cutting foreign aid, cracking down on immigration, addressing the longstanding Chinese exploitation of our economy... he SHOULD be popular.
I've had my disagreements with his tact and his political strategies, and he may not be successful, but he's doing things that no one else has dared, and it's about darn time.
