Joe Biden won Arizona last year...but by just 10,457 votes.
A lot has been made of Arizona flipping from red to blue last cycle.
But a 0.3% difference between winning and losing is nothing to feel comfortable about going forward -- especially with redistricting coming this year and possibly making my district much tougher.
The truth is that if we're going to build on those results we need year-round investment in voter registration and engagement.
