Based on Rasmussen's electoral college map tonight, Gov. Mitt Romney must win Florida to prevail against Obama.
Rasmussen shows Obama presently with 247 and Romney with 206 electoral college votes, and just six states in toss-up status (unlike RCP's ten in toss-up status): Colorado (9), Iowa (6), Wisconsin (10), Ohio (18), Virginia (13) and Florida (29).
My hunch is Obama figures Iowa is key to himself because he's counting on heavily union-dominated Ohio going his way, but Obama is so far making an effort not to telegraph this fact. Together those two toss-ups put him at 271, just enough to win. That's why he's spending so much time in Iowa after the pick of the 42 year old Rep. Paul Ryan by Romney, and why Byron York is fixated on Iowa in a recent column, but for the wrong reason. Iowa is more winnable for Obama than it is for Romney. In other words, Obama is theoretically right now conceding in a worst case scenario Florida, Virginia, Wisconsin and Colorado to Romney, which together give Romney only 267, not enough to win, because he believes he can win in Iowa and Ohio.
A Romney loss in Florida and an unlikely sweep of all the rest of these Rasmussen toss-ups means Romney still loses with 262.
Romney must prevail in Florida to win, if Rasmussen's map is correct. That's why Romney has focused on Florida right out of the box in sending Rep. Paul Ryan to Florida to appear there with his mother, reassuring the seniors on Medicare.
This election is going to be about the economy in general, but spending for Medicare is the tip of the Republican spear, while the president parries with appeals to the youth vote, which in Iowa turns out second only to Minnesota. For a state Romney at one time early decided not to contest in the primaries, Sen. Rick Santorum's narrow victory there identified Iowa to Obama as a state vulnerable for a candidate Romney.
The Des Moines Register reports here on five visits to Iowa by Obama in recent days:
The sitting president of the United States is coming back to Iowa next week to do some more campaigning, on the heels of a super-sized three-day visit to the state last week.
Obama is spending so much time in such an insignificant place because of the electoral math somewhere else, combined with the probability of winning Iowa's youth vote.
