You can't call Florida a bellwether right at the moment. On election night it was clear Obama was going to win even had Romney carried Florida narrowly.
Oh, I absolutely
do categorize the state of Florida as a
bellwether.
I've noted that the Sunshine State has carried for all winners, except with the Democratic pickup presidential victors of 1960 and 1992, since the year 1928. Right around that time, the state's population changes became very noticeable. And throughout the decades, Florida eventually rose to its current slot at No. 4. And it's about to overtake New York for No. 3.
Every election since 1996 has seen Florida carry by a margin no greater than five percentage points in spread from the national numbers. But, there were also election cycles from 1928 forward in which the state played it closely. In between there were presidential winners who were enormously popular to a point they won Florida by margins at least 10 points in addition to their national margin. (Think of George Bush in 1988. It helped him narrowly hold the state, by about 2 points, when became unseated by Bill Clinton in 1992.)

In the last five election cycles, Florida has been no greater than five points in spread from the national margin. Noted already. That's a better trendline than the previous 17 cycles in which 12 of them resulted in carriage by 10 points and more beyond the popular-vote margin with the statewide of Florida. Yet, all but two of those elections from 1928 to 1992 saw the state go for the winner. 1996 was the start of a new trend. In the past, a Republican would win Florida excessively (meaning that pickup winner George W. Bush should not have struggled to win it over in 2000), and a Democrat would also win Florida excessively (when the party's base was in the south; it's 1960 marked that the starting point of the GOP tilt though Jimmy Carter won it above his national margin).
Of the Top 10 populous states, which have been carrying for the winners over long terms, right now it is Ohio and Florida which reliably go with either party and produce outcomes close to the national results. (King-making bellwether Ohio has been within five points in all elections since 1964, which marked its current unbroken streak of carrying for the winners.) This cannot be said of California (which voted for all winners but three during the 25 elections of 1900 to 1996); Texas (which was on a roll from 1928 to 1988, getting it "wrong" only in 1968); New York (which was more a bellwether in late-19th century to parts of the 20th century; an excellent record no less); Illinois (which was a bellwether from when the GOP first competed in 1856 going through the end of the 20th century); Pennsylvania (which, from all its presidential-participating elections, has a record of backing the winners on average of four of every five cycles); Georgia (which has a pitiful record because, as I observed, it supported just 15 of 25 winners from 1912 to 2008 and got it "wrong" again in 2012); Michigan (which boasts a similar record to Pa. but with a couple more errors and five disagreements with Pa. which included one state having a major-party candidate who didn't carry the other state from three cycles; the Wolverine State has been reliable three of every four cycles on average and seemed to have bellwether-like margins in 1984 and 1988, thus news media erroneously having described it as a "swing state"); and North Carolina (with seven errors from 1912 to 2012).
Yes, in this era where presidential winners are not carrying four of every five states on average, I'm more inclined to describe Florida (with Ohio) as being among a precious few
bellwether states. The way the electoral map is shaking out nowadays, no Republican nominee for the presidency of the United States is going to win election without the carriage of Florida. (Ditto with Ohio.) But when the Democratic party prevails, Florida will carry anyway even without mathematically needing it (which is the way it was when the Democrats had the south and every prevailing Republican from 1928 going forward carried the Sunshine State anyway without mathematical necessity). Florida is trending with country. (As are Ohio, Virginia, and Colorado. Next up: North Carolina.)
