Congressional Republicans know that the worst thing that can happen to them over the next six weeks is that Democrats in the House hold a vote separating the extension of the middle income and upper income tax cuts. Either just one vote on extending the middle income tax cuts. Or even two votes -- but separate votes on each. Now House Republicans are in the field pressing the Dems to hold one, single vote
-- thus combining all the tax cuts together and blurring the difference.
And the Dems aren't even on the field.
