So now they're comparing him to Joseph McCarthy, which is interesting, because historians have "discovered" that McCarthy was right after all, although liberals will never admit that.
Then there's this trope.
“I was compelled to vote no on Senator Kerry’s nomination because of his longstanding less-than-vigorous defense of U.S. national security issues,” said Mr. Cruz, who also questioned the commitment of Mr. Kerry and Mr. Hagel to the armed forces, though both served in Vietnam. Mr. Cruz has no record of military service.
The fact that Mr. Cruz has not served in the military is completely irrelevant to the issue of whether or not Kerry and Hagel are committed to our armed forces. Kerry, after all, was the one who met with enemy negotiators in Paris
while still serving as a Naval officer to advised them regarding the terms under which the US would withdraw from Vietnam and testified before Congress (lied being the more appropriate description) that US troops behaved like the armies of "Ghenghis Khan" routinely committing atrocities.
Many of us Vietnam veterans view Kerry in the same light as Jane Fonda; traitors who should have been hung from the yardarm. That they were not even questioned about their activities speaks volumes about the patriotism of far too many of our politicians.
Edited to add: Here's how I read the NYT article - Darn it! Ted Cruz is having an impact! Darn it!
