As part of his campaign platform, then-candidate Trump called for a litany of immigration reforms, including his trademark cry for a “beautiful” wall along the US-Mexico border.

Trump’s campaign, however, offered little detail on design, or how the wall would function in the rough border terrain. The administration has since revealed several prototypes, but the final plans remain ambiguous and unfunded by lawmakers.

Just before Thanksgiving, I received a call out of the blue from a friend of Oz Griebel, a well-known and very respected business leader in Connecticut, and a Republican. He began by telling me that Mr. Griebel is exploring a run for governor, and that I was on his short list.

“Short list for what,” I asked. “You know I am a Democrat, right? And, I believe strongly in gun violence prevention, social justice reform, and protecting our most vulnerable” among other issues.

“I didn’t change, the system changed. This system is terribly broken.”

That’s what Colorado State Senator Cheri Jahn wrote in her announcement on Friday, declaring that she’s left the Democratic Party and will serve the remainder of her term as an independent.

“The unaffiliated voters in my district and statewide deserve representation.”

This is a really big deal.

In the wake of the Republican tax reform bill, which has been hailed by supporters as the most significant revision to the federal tax code in 30 years, many Democratic states and city governments are looking for ways to work around the effects of GOP tax reform.
