Incumbent Republican Keith Self commands 87.5% trader consensus to retain TX-03 after dominating the March 3 Republican primary with 81% of the vote against challenger Mark Newgent, solidifying his position in this Solid Republican district (Cook PVI R+10). Democrat Evan Hunt advanced unopposed in his primary but confronts formidable barriers, including Self's 2024 general election win by 25 points (62.5%-37.5%) and fundraising edge ($130,812 cash on hand versus Hunt's $31,046 as of late March). With no public polling and no major developments in the past 30 days, district fundamentals and incumbency drive high Republican probabilities ahead of the November 3 general election, though a national Democratic surge could narrow the gap.
