Are we having some sort of contest to see how many Senate seats Republicans can lose in 2020? (The answer is 22.) This latest court ruling that ACA is unconstitutional should be ripe just around that time. Do you think maybe millions of people facing losing their health insurance will be inspired to actually vote in their best interests? Talk about a great campaign issue! Republicans just keep on shooting themselves in the foot. Complaining about ACA is a great campaign issue for them to get their (shrinking) fan base worked up, but God Forbid they actually succeeded. The backlash would be huge.

It's like abortion in that sense. A wonderful issue to differentiate themselves from Democrats, but if they actually got it banned, the voters would turn them out en masse.
