USA: Why are right wingers defying the Coronavirus lockdown more than left wingers?

To complement your answer, the Pew Research Center has produced several reports which showcase the partisan divide in the US regarding attitudes towards scientific experts and expertise. For recent results:
• Democrats and Republicans differ over role and value of scientists in policy debates (August 2019)
• Key findings about Americans’ confidence in science and their views on scientists’ role in society (February 2020)
The other key theme I would add to this is individualism. US conservatives, Evangelical or not, generally embrace market individualism. Especially for secular-minded conservatives, individual economic and civil liberties are top of mind in a way public health (inherently collective) is not.

It’s simply because the Democrats are the ones who introduced the lockdown.
