think of leftists as “antimatter”
it is necessary for the existence of life and the universe that they not win too many of the collisions
of course, it would be best if the margin of (political) victory were a lot better than 1% over time..... ;^)
It's a compound interest problem over sufficient time and 1% is enough give total victory. There's pretty much no anti-matter around that we can see. Anti-matter that dies in our instruments before you can say "Obama gave us health care!" doesn't count.
