Excuse me friends, but it seems you're in dire need of reorientation to reality.
This pledge pledges nothing to Grover Norquist. It only pledges to the taxpayer. Here is an example of the pledge, for the U.S. Senate
http://www.atr.org/userfiles/Senate Pledge(2).pdf
"I, ______________ , pledge to the taxpayers of the state
of ______________ , and to the American people that I will:
ONE, oppose any and all efforts to increase the marginal income tax
rates for individuals and/or businesses; and
TWO, oppose any net reduction or elimination of deductions and
credits, unless matched dollar for dollar by further reducing tax rates."
If you repeat otherwise again, then I can only conclude that you cannot read or that you are posting in bad faith.
And you know what? Politicians are perfectly capable of making this sort of pledge verbally to their constituents. This is no more or less binding than those pledges - the only consequences are the possible ramification of being caught lying to your constituents. Recall George Bush's pledge for no new taxes and the support it garnered him; recall the outcry when he violated that pledge.
Now, if you happen to be some fool that wants to pay higher taxes, well first of all, psychiatry works, give it a shot. Second of all, here's a link to where you can just donate directly to the treasury, go nuts:
Gifts to the United States Government: Questions and Answers: Financial Management Service ...
... and oh yeah, third of all, a politician can still make pledges to his constituents to assure them and gain their vote. If this pledge is counter to your wishes, well, your option is to not vote for them. If they win anyway, they're still obliged to hold to their pledge because that's why others chose to vote for them. They choose to represent your interests by not coercing more money from you (the bastards!).
Are we done with the nonsense, now?
