The “avalanche” (in George Soros’ words) of vulnerable Dems continues to come down on the Ohio Democratic Party. The New York Times has a story on how Charlie Wilson in OH-6 and Zack Space in OH-18, previously considered unstoppable, are now in tight races:

Here in St. Clairsville, an Appalachian town on the eastern edge of Ohio, the new investments by Republican groups have become apparent in recent days. Television and radio advertisements are aimed at Representatives Charlie Wilson and Zack Space, both Democrats who were elected in 2006, while new pieces of literature tying the men to President Obama and the House speaker, Nancy Pelosi, are arriving in the mail.
The two districts, which come together like long and jagged pieces of a puzzle, are among Ohio’s most rural and conservative. Yet even though Senator John McCain carried the region over Mr. Obama in the 2008 presidential race, Republican leaders had initially decided against making major investments because they believed there were greater opportunities elsewhere in the state and because both congressmen had strong connections to the area.
But polls taken for their Republican candidates showed steady signs of promise, party officials said, so over the weekend the national party made an initial expenditure of $350,000 on television commercials in both districts. Democratic strategists believe that the spending is either designed to be a head fake, so they are drawn into spending money on the races, or a signal to outside groups, who are prohibited from coordinating with the party, to begin making their own forays into the contests.
For months, Bill Johnson, the Republican challenger to Mr. Wilson, has drawn little notice and has struggled to raise money. But last week, things began to change.[…]
“They are going to try to pick off what they think is low-hanging fruit,” Mr. Good said. “But the only way Charlie or Zack can lose is if our party does not get out and vote.”

Speaking for myself, I interviewed Bill Johnson nearly a month ago. He’s definitely going someplace this November.
