More importantly - to use Third Way reports as your basis is the best way to get laughed out of Congress - they are an advocacy group that is trying to battle conservatives by molding a new group called "progressives" - a bunch of former "liberals" that are trying to take the south back for the Democratic Party.
And finally the Congress is already working on a bill that adds two more years to the prohibition of taxes on the internet 47 U.S.C. 151 - the bill is H. R. 1685
Just to clear up some misconceptions - bills get introduced every day that dont even make it to a committee let alone to a full vote of the house or representatives - you really ought to look at the bill they introduced earlier this year - it abolishes the IRS and gets rid of the income tax system completely and replaces it with a flat tax - and its still around - H.R. 25 and the Senates version S. 25
Now there's something I would vote for
All of this grandstanding by congressmen (and I guess women in this case) is usually just to grab attention to their cause - which in this case happens to be "furthuring the attention to the progressives stand in preparation for the 2008 election.
