In the U.S., virtually every city near or above 1 Million occupants is Democrat. The younger crowd is most easily fooled into the idea of free stuff.
In Colorado, the Denver complex has long fallen for this deceit.
To make things worse, Boulder is a hard-left college town. Colorado Springs is growing enough that it recently started the swing left, but there is still hope. Pueblo is basically Hispanic, (legally) but not noticeably Democrat. However, comma, it is growing. I wish there were a good Republican politician to run for Governor.
