He's one of the few conservatives left in the part of California that is ignored by the left since it's mostly minorities, conservatives, and other riff raff working the land. They don't get invited to Bay Area fund raisers so you don't hear much about them. And don't look for a place to plug in your Tesla in Fresno. Wrecking yards, they got as wages have been falling and poverty increasing for ten years.
Aside from that he's one of the few conservatives still standing, which is a skill in and of itself. Right now he's in the bulls eye for not spiking the investigation into intelligence agencies going rogue and getting into the business of choosing America's political winners and losers. The result of this so far is to wipe the smile off Rep. Adam Schiff's face, and dampen the drumbeat of accusations that Trump is a Russian spy, and turn the fire hose of light and truth on the Obama Administration.
The last I check he had a net worth of ~ $85K, so it can be inferred that he's not on the take like most politicians.
So aside from that, he's one of the last honest men standing in California and the DNC is after his scalp.
BTW, I'm not one of his constituents, but I sold for years in his territory and he is well regarded by people I associated with.
