we haven't had a republican vote for a income tax increase since 1990. &amp;amp;gt;&amp;amp;gt; and this was your doing? &amp;amp;gt;&amp;amp;gt; i helped, yeah. &amp;amp;gt;&amp;amp;gt; it began with the simple idea of getting republicans all over the country to sign an oath called "the taxpayer protection pledge," promising their constituents that they would never, ever vote for anything that would make their taxes go up. &amp;amp;gt;&amp;amp;gt; that's speaker gingrich's tax pledge back in 1998 -- . &amp;amp;gt;&amp;amp;gt; and once they sign the pledge, grover norquist never forgets.
