Wow, Senior Citizens make up the R base in Florida National Politics?! WOAH!
To be honest, this article is well constructed but tells a story we all(hopefully all, we are on a political forum) know. Latinos, especially Cuban Americans, are moving to the Democratic party up and down the ballot, while retirees are moving into the state, keeping it a tossup. Florida appears to be a state that will be in limbo for some time, as the flow has been constant on both sides. There is no growing metropolis like Phoenix to finally tip the balance, nor is there a rural shift that can occur like in the Rust Belt. Turnout is the only way to win in Florida.
According to an analysis by a prominent Democratic strategist in FL, both turnout and managing margins are needed to get a Democratic victory. This can be seen by the decisive factors in the (narrow) Democratic losses this decade:
2010: Insufficient turnout in Democratic base counties
2014: Increased Republican margins in Northern FL
2016: Increased Republican margins in suburban/exurban counties surrounding I-4 corridor
