You forgot ~/.bash_profile. It is recommended that ~/.bash_profile source
~/.bashrc, but it is not required.

PS1 is normally exported I think, and .bashrc might be read by a subshell.
For example, a process tree like:
"/sbin/login"
+"-/bin/bash"
+"/usr/bin/emacs"
+"/bin/bash"
Might send up reading ~/.bashrc twice.
