OK. Let's suppose they dump their abortion stand, or just lighten up from all abortions, all the time, from day 1 of a pregnancy to 3 yrs. after, that gets rid of the NOW gang and Emily's list (including a lot of Rino women.) Then if they dump the gays, that gets rid of a handful of people, but a ton of $. Then they adopt some reasonable stand on illegal immigration, that loses a boatload of voters signed up at the DMV, the 10 gazillion illegals who already live here who are already on the voting rolls, and worst of all, it makes Soros and all his money and "open borders" people run like hell. And they gain in the red states what portion of Dems voting Repub and Repubs? Looks very risky to me.
Also, I think Soros is dispensable to the Democrats. Look at what he did for them this time: a near-total disaster.
