Thousands pack Plano rally as Democrats target Collin County shift

A few thousand Democrats packed an event hall at the Plano Event Center on June 2, turning James Talarico’s campaign stop into something bigger than a rally in Ken Paxton’s backyard. In a county that has long anchored Republican power in North Texas, the size of the crowd signaled why Democrats now see Collin County as one of the most important political battlegrounds in Texas.

The numbers help explain the attention. The U.S. Census Bureau estimated Collin County’s population at 1,297,179 on July 1, 2025, up from 1,064,465 at the 2020 Census, a 21.7% increase. The North Central Texas Council of Governments said the county added almost 76,000 new residents in one annual estimate cycle and more than 64,700 in the next, putting it among the fastest-growing counties in the region and the country.

That growth has also made the county more diverse and more educated. Census QuickFacts shows Collin County is 23.3% foreign-born, 31.2% of residents age 5 and older speak a language other than English at home, and 56.2% of adults age 25 and older have a bachelor’s degree or higher. For Democrats, that mix is evidence that the old suburban map is not fixed anymore.

Talarico’s appearance was wrapped into a broader message about the 2026 Texas Senate race, where Ballotpedia lists him as the Democratic nominee and Paxton as the Republican nominee for the November 3 general election. The crowd was described as roughly 3,600 to 4,000 people, making it Talarico’s largest North Texas audience yet and giving Democrats a visible boost in a county that still helped Donald Trump win in 2024.

For Paxton, the setting carried extra weight. Collin County has helped launch or sustain the careers of Republican figures such as Jeff Leach, Keith Self and Abraham George, and it is also the county where a grand jury indicted Paxton in July 2015 on felony securities-fraud charges. That history makes the county more than just a home base; it is part of his political identity and part of his baggage.

State Rep. Mihaela Plesa told the crowd that flipping Collin County would matter far beyond county lines, and Talarico cast the moment as a sign that Republicans see his movement as a threat. The rally centered on schools, affordability, corruption and state politics, issues that continue to shape suburban conversations from Plano to McKinney, Frisco, Allen and Wylie. Whether the crowd marked a lasting shift or a single-night surge, it showed that Collin County is no longer being treated like safe Republican ground.
