Judging from Tuesday's results, the president had a strong, smart political team backing him and I guarantee you they knew the visits to Joplin would net them few, if any, votes. They were simply the right thing for a United States president to do.
Joplin's anti-Obama (or pro-Romney vote, if you prefer) is examined in a Daily Kos post:
So....getting to the vote. One might think that the residents of Joplin would finally see through the GOP bellows against the EPA, against the 47% who are 'taking stuff', against 'big government'. One would think they would have been appalled at Willard Romney wanting to eliminate FEMA and let the private sector 'help' at huge profits to themselves at the expense of taxpayers. Let's see.Joplin is mainly in Jasper county, MO but part of it lies in Newton county. Let's check out the vote totals for both in the 2012 presidential election.
JASPER COUNTY: Obama 12,808/Romney 31,345NEWTON COUNTY: Obama 6,425/Romney 18.179TOTALS Obama 19,233/Romney 49,524
While these numbers are discouraging, the population of Joplin pre-tornado was a smidgen over 50k so it's possible that the Obama numbers are coming primarily from Joplin - but it's still less than half of the existing population of Joplin and comes from a metropolitan area of over 176k - a metro area that did pretty well with the federal funding as it provided much-needed construction jobs. If this isn't voting against your own self-interest I'm not sure what is. Or it's possible that they figure that they have their federal funding and will now vote to ensure that other such stricken communities won't have the same opportunity to rebuild that they did.
