If you know a little something about Excel (or in my case, OpenOffice Calc, which has the same basic functionality), it’s fairly straightforward to calculate the vote totals and percentages for various candidates in various county, state, or federal districts. These districts are well-defined, and by that I mean they contain a certain number of precincts in their entirity, and two districts of the same classification (i.e., two State Rep districts) have no overlap between them. (That actually isn’t exactly right, but it’s close enough to not worry about.) It’s not the same for determining the vote in the city of Houston versus the rest of Harris County. City boundaries do not conform to precinct boundaries. There are numerous precincts that are part Houston and part not-Houston. When I first tried to do this, after the 2008 election, I wound up counting a number of non-Houston votes as being from the city, which had the effect of underestimating the Democratic percentage by two or three points. After getting some feedback on this, I refined my methodology and got a result that I thought was more accurate. It’s definitely an estimate, but I’m confident it’s in the ballpark.
This year, I have the benefit of the city of Houston bonds and charter amendments on the ballot, which identify all of the precincts that contain city of Houston voters. Obviously, I don’t want to count all of the votes in each of those precincts as being city of Houston, for the reasons given above. You can look at the individual precincts and see a handful of bond votes but hundreds or thousands of Presidential votes, so you know you can’t count the whole precincts. What I wound up doing was counting the votes in any precinct that had at least ten Yes votes for Proposition B, the parks bond that was the biggest winner among the bonds, as Houston precincts. It’s not exact, but it’s close enough. Here’s what I got from doing that:
Candidate Votes R Votes Pct
=====================================
Garcia 381,103 211,886 64.3%
Obama 371,755 242,953 60.7%
Ryan 370,181 225,952 62.1%
Trautman 367,587 226,185 61.9%
Hampton 359,110 227,134 61.2%
Sadler 356,630 242,658 59.5%
Petty 356,110 225,061 61.3%
Bennett 353,317 234,256 60.5%
Henry 342,986 240,103 58.8%
Oliver 342,701 252,168 57.6%
By this calculation, which remember is as much approximation as anything else, Obama lost 0.3 percentage points from 2008, while Adrian Garcia lost about a point and a half. This is consistent with the amount they lost overall from 2008, so again I feel pretty confident. You can see that Garcia, Vince Ryan, and Diane Trautman all attracted some Republican support, while Mike Anderson, Christi Craddick, and Mike Sullivan all drew Democratic support.
Here’s the flipside, non-Houston Harris County, which is simply the totals above subtracted from the overalls:
Candidate Votes R Votes Pct
=====================================
Garcia 230,860 310,551 42.6%
Ryan 215,781 326,609 39.8%
Trautman 214,896 326,012 39.7%
Obama 213,696 341,913 38.5%
Petty 208,702 321,146 39.4%
Hampton 207,229 326,415 38.1%
Bennett 206,689 328,248 38.6%
Sadler 206,325 338,539 37.9%
Oliver 199,443 343,351 36.7%
Henry 198,206 334,588 37.2%
Pretty much what you’d expect based on the first set of results, with the exception of Paul Sadler sliding down a few spots, for which I’d blame – again – his lack of resources. I read these amazing stories about the turnout effort in Ohio, and I ask myself again what that might look like if it were ever tried here. I don’t really have anything more to add to this, so I’ll leave it here and we’ll continue with more analysis later.
