As Election Day draws near, Texas voters are hearing a lot about poll numbers. Juan Sepulveda, a San Antonio native who helped run President Barack Obama’s campaigns and now serves on the Harvard University Board of Overseers, offers practical guidance on what polls really tell us.

Polls Are Snapshots, Not Predictions

“First of all, it’s a snapshot,” Sepulveda said. “It’s for that particular point, for that particular day.” He stresses that a single poll reflects opinions at the moment it was taken, not a forecast of how the election will turn out.

Why Look at Averages

Sepulveda recommends voters consider the average of several polls rather than relying on any one survey. Averaging smooths out the quirks of individual methodologies and gives a more reliable sense of overall trends.

Margins of Error Matter

Fewer people are answering calls from pollsters, which can widen a poll’s margin of error. “There is no single margin of error that makes a poll reliable,” Sepulveda explained, “but a wider margin can indicate that pollsters have had more difficulty reaching or measuring voters.” When a race’s results fall within that margin, the contest is effectively tied.

Tight Races in Texas

Several high‑profile Texas contests—including the governor’s race and a U.S. Senate seat—have been within a few percentage points in recent polling. Sepulveda notes that when the numbers are that close, the margin of error can swing the perceived lead either way. “If I see a race as tied, even though one candidate has been ahead in most of the polls, I tell people it’s within the margin of error. It could go either way,” he said.

Polls Can Motivate Voters

Close numbers can also influence voter turnout. When voters hear a race is tight, they may feel their vote matters more and be more likely to cast a ballot. “Campaigns are hoping that happens,” Sepulveda added, noting that energized voters are crucial in deciding close elections.

Takeaway for Voters

Sepulveda’s advice for Texans is simple: treat any single poll as a moment‑in‑time snapshot, look for the consensus across multiple surveys, and pay attention to the margin of error. By doing so, voters can better gauge the real state of a race and decide how to participate.
