You are correct about Reagan nominating Justice Anthony Kennedy but only after the Democrats savaged his first nomination, the conservative Robert Bork. The Democrats and 6 RINOs blocked Bork. The Democrats and RINOs stuck together blocking a conservative to prevent the court from going solidly to the right. Reagan then had to nominate a moderate to fill the vacancy. Spinless Republicans roll over and approve the nominations of radical leftists like Ginsburg, Kagan, Sotomayor, ad nauseam. Democrats fight. Republicans just enjoy the perks of the office.
