Getting my Head Around Passage of SJR H

So on Wednesday this week, the Senate passed SJR H, which caps property taxes even more than they are already. I was in DC when it happened, working with Sam, who took over handling it on the ground. Coming back...I am having a hard time getting my head around how it could have passed with 29 votes. I totally get the popular nature of capping any tax. But, the biggest thing that people and legislators have complained about regarding our property tax system is the big jump in Taxable Value to State Equalized Value when a home sells. This actually just exacerbates that! So why is this being hailed as such a great idea? And that's secondary to the fact that it would have a minimal impact on some homeowners while having a devastating cumulative effect on our communities. It's hard to wrap your brain around...
