Democrats have won recent elections but face historical headwinds in 2010. Republicans are spending millions on attack ads through outside groups. The DCCC plans to stay on offense, highlight Republican problems, and capitalize on the weak Republican brand. Recent special elections show Democrats effectively countering Republican messages and energizing voters. The tea party movement presents challenges for Republicans by pushing extreme candidates and splitting the Republican vote with third party candidates. Questionable Republican candidates in some races could also aid Democrats. Support for Democratic candidates is encouraged.
