So the fact that Clovis posted a low-budget web video Wednesday trashing Rubio for his work on the Senate immigration reform bill is an ominous sign for the Florida senator and would-be presidential candidate.

Despite recent hand-wringing about the flawed nature of the Iowa caucuses, the state is all but assured to keep its leadoff position in the 2016 nomination process. If Rubio runs, he’ll have to make nice with Iowa conservatives. They just might not be nice to him.

“I might have expected this out of John McCain,” Clovis says of the immigration bill. “But we certainly didn’t expect this out of Marco Rubio. Marco Rubio was elected by conservatives in the state of Florida and he was supported by conservatives all over the United States. And there is nothing conservative in this bill.”
