It has been my experience that the conservative people, who have moved from the Northeast US to Florida, become very active in conservative political organizations in Florida.
The Conservative Northeasterners know very well how the leftists destroyed their state and do not want the same thing to happen in Florida.
A lot of the Midwesterners Florida has long gotten are OK. Sure they’re not Southerners, speak with funny accents, wear black socks with sandals and have to be properly educated on Southern cooking - but by and large, they’re our kind of people so they’re OK.
Sure we get a few conservatives from the Northeast but damn do we get a ton of aging Leftists who’ve come to our state to die. Even worse are younger northeastern Leftists who come to Dade/Palm/Broward counties and immediately try to start making Florida into South New Jersey. Orlando has seen an influx of outsiders and is in the mushy middle. Tampa and Sarasota etc remain mostly traditional Florida ie Southern and conservative. North Florida - say Daytona westward all the way to the Florabama border is Dixie. ie loves the military, low tax, pro gun, traditional. It’s North Florida that keeps Florida in the red column far more often than not.
