Traditionally Americans are quite suspicious of their government. The battles over 1st Amendment free speech and 2nd Amendment gun rights, among many, are a testament that the sentiment is still widely held.
Only China does it better ... the oppression, of speech, that is, as evidence by a video of CCP police roaming subway trains, reading every subway commuters' cellphone for social media content. As if CPP's ability to monitor centralized servers isn't cutting it anymore.

Traditional Americans are few and far between these days. Decades of "liberal" education pushing a rose colored view of strong central governments have changed the American Culture this is why you see younger voters increasingly looking to government not community to solve their problems.
In your example where Democrats support the 4th amendment, what except if a random person says you are armed then the 4th goes out the window, except if you are deemed to be rich then the 4th goes out the window, except if you have the "Wrong" opinions then the 4th goes out the windows
Democrats like Republicans only support the 4th, and every other amendment to the point where it supports their narrative and desire for power, the second the constitution is deemed to stand in the way of their power well it is document that should be ignored "for the greater good"
