Michael Barone has taken a look at the results of the Massachusetts Senate race on a district by district basis (among the Mass congressional districts) and notes the following:
<blockquote>Coakley carries districts where Obama got 65% or more of the vote and runs essentially even in the district where he got 64%, and Scott Brown runs ahead in districts where Obama got less than 64% of the vote.
Lets extrapolate those numbers to the nation as a whole and assume that a district that voted 64% or more for Obama is safe for Democrats even under the most dire of circumstances. How many such districts are there? Answer, according to this source: 103. The other 332 districts voted 63% or less for Obama. Interestingly, there are more 64%+ Obama districts in the West (36) than in the East (27) and more in the South (21) than in the Midwest (19).
All but two of the 103 Obama 64%+ districts are represented by Democrats. The two exceptions are Louisiana 2, where Republican An Joseph Cao beat Democrat William Cold Cash Jefferson in a December 2008 runoff, and Florida 19, whose incumbent Robert Wexler resigned and a special election will be held in April. And, yes, it will be amazing if this heavily Jewish district in Palm Beach and Broward Counties elects a Republican; heavily Jewish Brookline and Newton voted heavily against Scott Brown in Massachusetts. read more »
