Matthew Dowd is no squishy liberal, a “snowflake.” He’s a long-standing Republican political operative.

He also serves as a broadcast and cable news “contributor” and, yes, he is a Donald J. Trump critic.

He sent out a tweet just a while ago that reiterated something he said this morning on ABC News’s “This Week” program: As i said on @ThisWeekABC to give some perspective: “Benghazi was a 4 year investigation, there were zero indictments. The Clinton emails was a 2 year investigation, there were zero indictments. The Mueller investigation has been 14 months, there have been 23 indictments.”

“Benghazi” involved a terrible firefight that occurred at a U.S. consulate in Benghazi, Libya on the watch of then-Secretary of State Hillary Rodham Clinton; the “Clinton emails” also involved the former secretary’s use of her personal email account while serving in the State Department.

The Mueller investigation? Well, it’s that probe that is occurring at the moment to explore questions relating to Trump’s presidential campaign and its possible relationship with the Russian government … among other things.

GOP hardliners want Robert Mueller’s probe to end. Now! They forget about the length of time they insisted on maintaining while GOP members of Congress looked at Hillary Clinton’s conduct.

All that time, money and effort produced zero indictments. None, man!

Mueller — who, by the way, also is a Republican — so far has harvested a much healthier crop of criminal complaints.

And, no, this isn’t a “witch hunt.” It is a serious investigation being conducted by a serious public servant.
