Harris County added more than 11,000 voters to its rolls in the final week before the registration deadline, the last wave in a surge of half a million new Texas voters since the March primaries.
Democrats are most likely to benefit from the increase because new voters, many of whom are young and/or nonwhite, are more likely to support their party, University of Houston political science Professor Brandon Rottinhaus said.
“There is a long legacy of Democrats seeking to get more people registered, and the investment is likely to pay off,” Rottinghaus said. “This is a moment where there’s going to be a lot of nail biting from Republicans on election night.”
More than 66,000 residents registered to vote in Harris County since the spring, more than any other Texas county, according to the Texas Secretary of State. Since the 2014 midterms, Harris County has added 280,000 voters.
Rottinhaus cautioned that there is a poor correlation between voter registration and turnout. Even as more eligible Harris County voters have registered since the 1990s, turnout has declined. Republicans, he said, are hampered by their past success since they already have registered most of their potential voters. Democrats have more room to grow, he said, especially with Latinos, African Americans, new citizens and young people.
See here and here for some background. I’m sure what was intended in that last paragraph was that while overall turnout has gone up, at least in all of the Presidential year elections in the county, the percentage of turnout of registered voters has declined. Far more people voted in Harris County in 2016 than in 2008, for example, but the rate of turnout was slightly lower, precisely because there were so many more registrations.
Anyway. Putting the numbers together, we’re at 15.8 million statewide, and around 2,316,000 in Harris County. Keep that latter number in mind when you read this.
County Clerk Stan Stanart predicts up to a million Harris County residents could be casting ballots in a string of hotly-contested races.
One million voters in the county would be a lot for an off year – a record amount, in fact – but it would still only represent about 43% turnout. The high water mark so far is 2010, with just under 800K voters, and 41.7% turnout. Can we beat that? It feels a little crazy to say so, but I think we can. I also think we’d have a very different electorate with that one million this year than we did with that 800K eight years ago. I think we’re headed for new heights statewide, too. It’s on us to make sure the mix of voters is what we want it to be.
