The following is an excerpt from a campaign speech.
Senator Baker: My opponent, Candidate Rothmore, has called for increased taxes to fund programs that help the long-term unemployed of the state. Such action would address an immediate symptom for a select group, without doing much to address the overall problems we all face. Only through lowering taxes can we stimulate the growth of small businesses, which will revitalize the state's whole economy. That, in turn, will result in greater prosperity and in more jobs, including jobs for those who have been unemployed for a while. Through lowering taxes, everyone wins, and those currently unemployed get the best help the economy can provide --- a real job.
