Twitter was all... umm, atwitter with news that US Representative (class of 2010) Cory Gardner would jump into the US Senate race in Colorado against Democrat Mark Udall. With the 2014 mid-term elections right around the corner, the news for Democrats seeking re-election to the US Senate is not getting better. It seems that the list of troubled incumbents grows by the week, and there's more potential targets on the horizon. Early polls have the Republicans potentially taking back control of the US Senate to go along with their control of the US House of Representatives. Colorado was not supposed to be competitive, but Obamacare has some serious legs these days.
