I’m not saying Ryan will lose but Cantor was claiming internal polling showing him with a 34 point lead and he lost by 10+ points to Dave Brat. These type of primaries usually don’t turn out voters. If angry voters show up which they usually do Ryan may be in for a surprise. We’ll see. Ryan’s district is only +3 unlike the VA 7th which is R +10 or even the Kansas District 1 which Huelskamp lost which was R+22. Now if Democrats wanted to screw GOP they could vote against Ryan but that is a rarity. Ryan is more milquetoast today than he was even 4 years ago and nothing Democrats like more is weak Republicans in leadership positions.
Comparing Candor to Ryan is a fools errand.
Unless turnout is insanely low, I personally would not hold my breath on Ryan losing his primary.
