Its because liberals are amoral:
EVERYONE would be insisting on a Republican dropping out of primary if diagnosed with PD. IF they ran knowing they had it, there would be liberals setting themselves on fire in the thousands...and a Republican WOULD be impeached.
This goes to show you how power-mad liberals are. They will lie, cheat, steal, and do ANYTHING, no matter the moral consequences to achieve and hold power.
Just a couple of months ago they were getting on Trump for having high cholesterol or something. Saying he should resign. Yes, liberals are amoral, delusional, selfish, etc..
