Former Congressman Rob Simmons (R-CT) has announced that he is going to challenge Sen. Chris Dodd (D). Simmons narrowly lost reelection to his House seat in 2006, but held it for three terms and ran well ahead of George W. Bush to knock off an incumbent Democrat in 2000. A recent poll showed Simmons leading Dodd 43 percent to 42 percent, well within the margin of error.
