Morris is such an idiot and is wrong so often, it makes you wonder how he could possibly help get anyone elected.
As long as the bill looked like having a chance, the Dems could look forward to support from the millions of newly legal immigrant voters that it would create, who would more than offset the loss of the disgusted working-class union-member Dems whose jobs were taken away from them and given to the "newcomers." But when the senators saw that the bill was tanking and that they didn't have enough votes to rescue it, they scurried like a pack of jackals to secure their own re-election prospects, figuring that a "No" vote would restore their credibility with their traditional base.
As for Morris, no argument. His only redeeming feature is that he seems to despise Hitlery... although sometimes I wonder about that, too.
