The first-ever GOP midterm convention in Dallas is drawing empty seats and no-shows, a bad sign for Republicans defending tight races.

• Organizers expected 20,000 people and hyped it as bigger than the 2024 convention; the hall is far from full.
• Lawmakers were asked to pay $25,000 and up to attend, and prices got cut when few people bought in.
• Of 60 candidates in competitive races contacted by CBS News, only four confirmed they would show up.
• Trump's approval has slipped to 32% in new polling, his lowest in that survey, as voters sour on prices and the Iran war.
• Israel, a centerpiece of the 2024 convention, is barely mentioned this time; the focus is tax cuts and culture-war fights.

Outlook: Republicans in swing seats look set to keep their distance from Trump as the midterms approach, with Democrats favored to take the House.
