Remember: Dean is a SOCIAL progressive and a FISCAL conservative.
http://en.wikipedia.org/wiki/Blue_Dog_CoalitionDifferences between the Blue Dogs and the DLC
Blue Dog Democrats tend to differ ideologically from another coalition of moderate Democrats, the Democratic Leadership Council (DLC). The DLC describes itself as new Democrat and positions itself as centrist while taking liberal positions on social issues and conservative positions on economic issues and trade. Democrats who identify with the Blue Dogs, on the other hand, tend to be social conservatives, but have differing positions on economic issues ranging from fiscal conservatism to economic populism. For example, most Blue Dogs are strong supporters of gun rights and get high ratings from the National Rifle Association, many have pro-life voting records, and some get high ratings from immigration reduction groups, which cannot be said for most members of the DLC. On economic issues, Blue Dogs span the spectrum from fiscal conservatives to supporters of labor unions, protectionism, and other populist measures, while the DLC tends to favor free trade.
A small number of newer Blue Dogs, however, hold positions closer to those of the DLC, and some Blue Dog Coalition members are also DLC members. Blue Dogs share with the DLC a desire to keep the Democratic Party grounded in their view of the political center, and to ensure that the party does not drift too far to the left of their own positions and no longer appeal to what they believe to be the majority of U.S. voters.
If the DLC are the "new Democrats", the Blue Dogs are almost surely "old Democrats", hearkening back to the party's past during the eras of Franklin D. Roosevelt and Harry S. Truman, and to the party's former electoral stronghold in the southern United States (see also: Boll weevil and Dixiecrats). Most members of the Blue Dog Coalition in the House represent rural districts, and a large proportion of them represent Southern states.
Differences between the Blue Dogs and the party's left wing
The Blue Dogs' moderate agenda in Congress has angered many in the Democratic party, as it often leads to them voting with the more conservative Republicans. In 2005, the members of the Blue Dog Coalition voted 32 to 3 in favor of the bill to limit access to bankruptcy protection (S 256). Congressman Collin Peterson was subjected to a heated round of questioning from colleagues in the Democratic Party over several votes where he strayed from the party line before being nominated as the Ranking Member on the U.S. House Committee on Agriculture, in what would otherwise have been a routine nomination.
On the other hand, some prominent Blue Dogs have also gotten strong support from progressive activists within the party, most notably Brad Carson of Oklahoma in his unsuccessful 2004 run for the U.S. Senate, John Tanner of Tennessee (whose Republican opponent in 2004, James L. Hart, was a radical eugenics advocate denounced by his own party), Jim Matheson of Utah, and Loretta Sanchez of California in her successful bid to unseat former Congressman Bob Dornan. Online fundraising efforts by liberal weblogs in 2004 named Brad Carson's campaign a top national priority. In some cases this support for Blue Dogs came about because the Republican opponent was seen as holding radical right wing views; in other cases the support is because in some states like Tennessee, Oklahoma, and Utah, a conservative Democrat is seen as the only kind of Democrat who can be viable at the polls. Some progressive activists also view the Blue Dogs as an important part of a Democratic Party big tent coalition, which will give the party important credibility with rural voters and social conservatives, while viewing the Blue Dogs as perhaps easier to swing to the left on fiscal and trade issues than the DLC.
Others in the party's left wing disagree, and have promoted the idea of running future primary challenges against both Blue Dog Coalition and DLC members in an effort to unseat Democratic Party members they view as unreliable or too conservative.
