Why? Because they're evil GOP bastards
 

Since the New Deal, Republicans have been on the wrong side of every
issue of concern to ordinary Americans; Social Security, the war in
Vietnam, equal rights, civil liberties, church- state separation,
consumer issues, public education, reproductive freedom, national health
care, labor issues, gun policy, campaign-finance reform, the environment
and tax fairness. No political party could remain so consistently wrong
by accident.
The only rational conclusion is that, despite their cynical "family
values" propaganda, the Republican Party is a criminal conspiracy to
betray the interests of the American people
in favor of plutocratic and corporate interests, and absolutist
religious groups.

Why? Because they're evil GOP *******s
