Maybe I'm really uninformed but classic liberal and libertarian are polar opposites. Republican policy is insanely archaic and constrains human freedoms much more that Democrats, so I'm struggling to see how a libertarian could support the guys putting militarized unaccountable secret police into our cities to terrorize and kill Americans. They're also much more into thought crimes than Dems, so I'm really wondering what you consider important?

What's objectionable about Democrat policy from the "libertarian or classic liberal" perspective?

Classic liberals and libertarians both favor individual freedom and limited government, but libertarians generally take the limited government bit a little further.

Militarized police is definitely one of the areas I disagree with Republicans on, along with abortion restrictions.

As for thought crimes, it's a toss up IMO, but I view Democrats as more likely to try to legislate against them.

I'd like federal government to be a whole lot smaller with more things being left up to state and local governments, so that's why I tend to side with Republican policy more often, but they're not much better either.
