“Republicans are pumping money into a series of Senate and House battleground states, unleashing one of their biggest advantages over Democrats as they seek to overcome electoral headwinds in the final weeks before midterm elections,” the Wall Street Journal reports.“Democratic candidates have mostly outpaced their Republican opponents in fundraising, but the GOP has maintained a significant lead among their network of super PACs and party committees—and are beginning to open the spending spigot in significant ways.”“Advertisers supporting Republicans across 10 key Senate races have spent more than $204 million in the first 18 days of September, according to AdImpact—$83 million more than those helping Democrats. It is a sharp turn upward from all of August, when the Republican spending advantage was about $9 million.”
