Will Darrell Issa lose in 2018?

[Vosem]

Yes, I don't see Issa surviving, considering the unpopularity of Trump, both broadly and in this district, and the likelihood of Democrats targeting this seat much more strongly in 2018 than they did in 2016. In fact, I tend to think it's pretty much lost for the GOP bar Issa either retiring or getting primaried (the latter I don't see happening, the former might be a possibility).

Also, CA-Gov has always been Issa's dream; he's far from a perfect candidate but he'd definitely be a better option than Peter friggin Thiel. If I were him, I'd go for that.

Hopeful both him and Rohrbacher lose.

If Democrats are serious about the whole "Russia is a threat to national security" thing, they should go after Rohrabacher hard.

[Vosem]

If Rohrabacher lost (which I'm skeptical of given how Dems have no bench there, though they could run a veteran or something), then Democrats probably already won the House.

I don't think this is necessarily true if there is a swing to Democrats in areas where Hillary Clinton did very well (ie, well-off suburbs), or indeed if there is simply a swing in Southern California, which in 2016 behaved like a world apart from the rest of the United States. A traditionally hawkish, wealthy, and Clinton-voting place with a congressman who has come to be somewhat out of step with his own district might swing very strongly even if the country as a whole doesn't.

As a very out-there suggestion, if Democrats want to make "the Russian threat" a part of their platform, and attack Rohrabacher on that issue, Michael McFaul could be an interesting candidate to run here.
