“Herd up”

From my Buddy:

See http://www.startribune.com/wake-up-and-see-the-trump-card-he-can-win/380327951/, which includes this interesting language:
For all the talk of Republicans who won’t vote for Trump, it’s quite likely that more than 90 percent will herd up.

And:

The identification with political parties is a psychological attachment that often forms in childhood. We are not handcuffed to our party but the tie is tight and has become more so.
A Stanford research team studied the reaction of Republicans and Democrats to the prospect that their child might marry someone from the other political party. In 1960 — no problem. Only 5 percent (or less) reported being upset by the idea. Our new hyperpartisan world has introduced a very different reaction by 2010. Nearly a third of Democrats were irked and almost half of Republicans were unhappy.

“herd up”? We are ostensibly farther out of the jungle since 1960, but we are increasingly tribal?

It was funny when I was a kid in the 60″s watching Candid Camera. Its not so funny now:
