为什么这很重要：每位参议员拥有一票表决权，但参议院席位并非生而平等——它们的“价格”也不尽相同。
Why it matters: Every senator gets one vote, but Senate seats aren't created equal — and they don't cost the same.
聚焦细节：与两年前一样，人口较少的州在2026年的每选民广告支出比率上显著更高。
Zoom in: Like two years ago the less-populated states have a dramatically higher dollar-per-voter ratio in 2026.
- 缅因州位居榜首，紧随其后的是阿拉斯加，该州预计将迎来7600万美元的广告投放——足以占据该州大部分广告库存。
• Maine is in first place, followed by Alaska, which is scheduled to be hit with $76 million in ads — enough to suck up most of the state's inventory. Between the lines:
深度解读：俄亥俄州在每选民广告支出指标上仅排名第五，但它有望连续第二个周期成为全美最昂贵的参议院竞选州——Sherrod Brown的卷土重来之战，比2024年他败给现任参议员Bernie Moreno（俄亥俄州共和党人）时的那场竞选更加昂贵。
Ohio is only in fifth place on the dollar-per-voter metric, but it's on track to host the most expensive Senate race in the country — for the second cycle in a row • Sherrod Brown's comeback bid is proving more expensive than his 2024 race, when he was ousted by now-Sen. Bernie Moreno (R-Ohio).
- 在新罕布什尔州，民主党参议院提名人Chris Pappas一直警告称他的竞选实际上非常胶着，双方都在大举投入以触达该州选民。
• And in New Hampshire, where Democratic Senate nominee Chris Pappas has been warning that his race is actually quite close, both parties are spending heavily to reach the state's voters.
大局观：两院的控制权都可能取决于少数几场关键竞选。
The big picture: Both chambers are likely to come down to a handful of races.
- 共和党人整年都在警告，如果总检察长Ken Paxton赢得初选，德克萨斯州的竞选将变得极其昂贵。他们的预言成真了。
• All year, Republicans warned that Texas would get really expensive if Attorney General Ken Paxton won the primary. They were right.
- 共和党外部团体在短短17天内就斥资高达1.31亿美元试图挽救Paxton。还有数千万美元可能在路上。
• Outside GOP groups spent a mind-blowing $131 million in just 17 days trying to rescue Paxton. And tens of millions more could be on the way.
- 但在北卡罗来纳州，全国共和党参议院委员会（NRSC）主席、参议员Tim Scott（南卡罗来纳州共和党人）曾预测该竞选可能耗资10亿美元，目前看来这场竞选的花费将低于2亿美元。
• But in North Carolina, where Sen. Tim Scott (R-S.C.), chair of the National Republican Senatorial Committee (NRSC), predicted the race could cost $1 billion, the contest looks like it will come in under $200 million.
- 共和党超级政治行动委员会正放弃该州的参议院竞选，将资金重新分配给更倾向共和党的州。
• Republican super PACs are abandoning the Senate race there as they reallocate money to redder states. The bottom line:
底线：共和党人在经费运用方面占据优势，尤其是在德克萨斯州和俄亥俄州能够触达的选民数量上。不过，双方都尚未找到如何以更少的预算有效接触选民的良策。
Republicans have a spending advantage, especially when it comes to how many eyeballs they're actually reaching in Texas and Ohio • But neither side has really figured out how to play moneyball and find a way to reach voters with a dramatically smaller budget.
